20-Minute Core Workout: Slow Sliding + Fast Tabatas

Today’s workout is a follow-up to the workout I posted a couple weeks ago. Same format, just different target muscle groups. While the title says “core,” your upper body will definitely feel the burn as well (brace yourself for some serious planking, people!). This 20-minute core workout will alternate between 2-minute slider sequences for the right then left obliques and 4-minute tabata intervals.

Before we get to it, I just want to thank you guys for all the feedback on YouTube, Instagram and here on the blog regarding last week’s workout! Hearing what you guys like and don’t like is so helpful in guiding my planning and formatting of future workouts. I like to switch things up so formats don’t get redundant, but hey, if it ain’t broke, don’t fix it. So many of you loved last week’s workout that we’re keeping it the same, just switching up the target muscle groups today.

20-Minute Core Workout: Slow Sliding + Fast Tabatas

Equipment You’ll Need:

  • Sliders (you can use a dish towel if on a hardwood floor or a paper plate on carpet)
  • Medium weight (I’m using a 10-lb kettlebell) — this is totally optional

This workout will take you 20 minutes to complete. If you’re looking for a longer workout, do it twice (once was plenty for me lol). You’ll do 2 minutes of slider work on each side (inspired by the megaformer work I teach at Btone!) followed by a bodyweight tabata (with the option to use a dumbbell). Here’s the general breakdown (rest for 30 seconds in between each section):

Slider obliques series on RIGHT
Slider obliques series on LEFT
Tabata 1
Slider obliques series on RIGHT
Slider obliques series on LEFT
Tabata 2

As with all workouts, make sure to warm up beforehand. I have a 5-minute warm up on my YouTube channel you can follow along with or just do your own. Modify as needed with all the exercises—I’ll explain how to in the video. 🙂

In this 20-minute core workout you'll alternate between slider blocks and tabata intervals.

20-Minute Core Workout: Exercise Breakdown

Slider Series 1

  • Snake (60) | In a plank position, feet on sliders, hands stacked under shoulders on an exercise mat, cross your right foot in front of the left and drop your heels so that you are heel-to-toe with toes pointing towards the left. You’ll twist through the waist, slightly lowering your right hip to do so. This is your starting position. From here, start bending your knees in towards your left elbow, sliding your feet forward. When you’re in as far as you can go, slide the feet back out, straightening your knees back into your starting position. As you do these, try to keep your hips level with your shoulders (don’t sit your bum onto your heels as you slide the feet in; engage your right sidebody to keep them lifted).
  • Low Teaser (30) | In a plank position, feet on sliders, hands stacked under shoulders on an exercise mat, cross your right foot in front of the left and drop your heels so that you’re heel-to-toe with toes pointing towards the left. You’ll twist through the waist, slightly lowering your right hip to do so. This is your starting position. Maintaining this leg position and keeping your knees straight, pike your hips slowly up into the air. When you’ve reached your peak, slowly lower back down to that twisted plank starting position. You are targeting your right oblique with these.
  • Arm Sliders (30) | Start in a plank position, hands stacked under shoulders, left foot on a slider. Crunch your right knee in towards your right arm and hold it as close to touching that arm the whole time. From here, you’re going to slide the right knee up towards your armpit and then down to hover by the wrist. Continue sliding the knee up and down, slightly rounding through the spine as you zip it up your arm to activate the core in a crunching motion. There will be minimal sliding on this one (your left foot might slide forward and back slightly but it won’t be huge).

Tabata 1

  • Side V-Ups | Start laying on your side, balancing on that bottom hip/side butt area with your bottom hand on the floor in front of you for support. Top arm is bent with hand behind your head and elbow out wide; legs should be extended and hovering off the ground. This is your starting position. From here, you’re going to crunch up and in, keeping your legs straight as you lift your torso up and in to meet them so that your sidebody forms a “v” shape. Use that bottom hand for support, but try to push off it minimally. Slowly lower back down and extend back out to a hover. Alternate side each interval.
  • Full-Body Crunch (option to use a dumbbell) | Start laying on your back with legs outstretched and hovering a couple inches off the ground. Holding a weight in your hands, arms should be outstretched overhead and hovering as well. From this starting position, crunch up, bringing your knees in towards your chest as you lift your shoulder blades off the ground and bring the weight up and over towards your shins. Extend back out, lowering to starting position. The goal is to never bring the legs and/or weight to rest on the ground when you extend back out.

Slider Series 2

  • Side Bear with Thread the Needle (60) | Start in a side forearm plank with your right forearm on the ground. I recommend staggering your feet on the sliders so that your top left foot is in front of the right. Keeping your hips at shoulder height, you’re going to bend your knees in towards your chest and slide the feet forward. As you do this, wrap your top arm around you, twisting your chest to the floor and threading the needle. As you straighten your legs back out to plank, untwist the chest and reach your left arm back up to the ceiling.
  • Twisted Pike (30) | Start in a forearm plank (or high plank) with feet on the sliders and drop your heels over to the right so that the lower body is angled to the left. Keeping the twist of the lower half, pike your hips up to the ceiling and back down, keeping the legs straight.
  • Single-Leg Crossbody Mountain Climbers (30) | Start in a high plank with your right foot on a slider and left leg hovering. Do a crossbody mountain climber, bringing the left knee to crunch into the right elbow and then the right knee to crunch into the left elbow.

Tabata 2

  • Bicycle Crunch Sit-Ups | Start laying on your back with your hands lightly behind your head, elbows bent out to the sides and chest open. Engage your abs, pulling your bellybutton down to the floor as you lift your legs off the ground about six inches to a hover. This is your starting position. From here, bend your right knee in towards your chest as you crunch your left elbow across to meet it, lifting your back off the floor like a twisting sit-up. Your left leg should remain outstretched in a hover as you do this. Slowly return back to the starting position and continue, crunching in the same direction the entire time. The goal is to keep the legs off the ground the whole time, but if you need to modify, your left heel can quickly rest on the floor in between reps. Alternate side each interval.
  • Walk-up-the-Wall Hollow Hold | Start laying on your back with your legs outstretched and hovering off the ground about 4 inches. For more support, place your hands under your bum; for a bigger challenge, have them outstretched overhead or elbows bent and fingertips by your ears. Crunch your shoulders off the ground and hold them there. From here, walk up an invisible wall, stacking one foot on top of the other until legs are pointing to the ceiling. From there, walk down in the same way.

In this 20-minute core workout you'll alternate between slider blocks and tabata intervals.

Hope you all enjoy your 4th of July! I’m taking this week off from teaching and for the most part from blogging as well (I may pop in with a post on Thursday or Friday). I’m hoping to have a lot of fun but also to catch up on studying—I’m so behind on my aromatherapy course!!

8-Minute Abs 2.0

8-Minute Abs 2.0 workout

UPDATED 6/27/17: This workout is still one of my most popular on Pinterest so I thought it was worth filming a video version of it. Revisiting old workouts is a great way to track progress, and I was pleased to find I could complete it with ease this time around (when I originally made it back in 2013 I distinctly remember being sore the next day). Maybe it’s time to make a 3.0 to follow up this 8-minute abs 2.0 workout …

Below is the original blog post with the addition of the new video.


We’ve all heard of 8-minute abs, but have you guys ever watched the original workout video? It’s…well, it’s special. And by that I mean it was filmed in the late 80s/early 90s, the spandex is on a whole new level of not OK, and the instructor’s commentary is pricelessly cheesy. Lots of “hang in there, gang!”

That being said, it’s not a bad ab workout, and I’ve done it countless times. The problem is, if you don’t switch up your workout routine, any fixed sequence is going to eventually stop being challenging. 8-minute abs quickly became an easy joke of a workout for me, and it was time to give it a serious makeover. Not just regarding the wardrobe (c’mon man, the bright blue spandex shorts with tube socks combo should be illegal), but with the exercises as well. I kept the structure of the workout the same, and switched up most of the ab movements. The result was an 8-minute abs 2.0 workout that actually challenged me again.

And before we get to the workout breakdown, how sick are the Nike running leggings I’m wearing?? I’m obsessed and trying to wear them as much as possible before summer hits—think they’d pass as Casual Friday-appropriate? I may test that boundary…

8-Minute Abs 2.0 workout

8-Minute Abs 2.0

Equipment I Used:

You’ll do each move for 45 seconds and move immediately on to the next without taking a break. The last move (elbow plank) is only held for 30 seconds. I just set my Gymboss Interval Timer for 11 rounds of 45 seconds of work and 0 seconds of rest and then watched the timer on the last round to end it at 30.

8-Minute Abs 2.0 workout

  • Leg Lifts: Laying on your back with hands under your bum for support, lift legs off the ground and up, perpendicular to the ground (keeping them straight the whole time). Lower.
  • Side V Crunches (Right): Start laying on your side with bottom arm stretched outwards on the ground for support. Do a side crunch, lifting your legs up and crunching them in to meet your elbow and raised torso.
  • Side V Crunches (Left)
  • Toe Touch Crunches: Lay on back with legs lifted perpendicular to the ground. Crunch up, reaching your hands towards your toes (you don’t actually have to touch them—I can’t, anyway haha)
  • Cheek-to-Cheek Plank: Start in an elbow plank position. Keeping shoulders level, twist your torso to lower your right hip to the floor. Return to plank position and then twist the other way, lowering your right hip to the floor.
  • Side Plank Lifts (Right): Start in a side plank position. Lower your hips towards the ground, and then lift upwards, crunching into an arch passed your original straight plank position. Continue lowering and raising.
  • Side Plank Lifts (Left)
  • Seated Leg Scissors: Sit with hands lightly on ground by your sides for support, lean back slightly and lift legs off the ground. Crisscross them back and forth keeping toes pointed, left over right then right over left, and so on.
  • Butt Lifts: Lay on back with legs lifted perpendicular to the ground. Lift butt straight off the ground, reaching toes towards ceiling, and then lower. Try not to rock back and forth too much (the momentum makes the exercise easier, but you’ll get a better workout from slow, controlled lifting and lowering).
  • Windshield Wipers: Lay on back, legs perpendicular to the ground and arms outstretched for support. Lower your legs to the right, twisting your hips, until they are just hovering above the ground. Lift back to starting position and over to the left side. Continue back and forth in a windshield-wiper motion.
  • Elbow Plank (30-sec): You know the drill!

My parents’ dog Ginny was visiting while I shot this workout and between high-fiving me in the face with her paw and running in front of the camera every 5 seconds, I would say she definitely is not a proponent of fitness. Had to give her a little loving scolding: 🙂

Stay tuned for 8-minute abs 3.0—I’m sure after a few months, my muscles will have mastered and become bored of this one as well!


10-Minute Lagree Fitness Core Workout You Can Do at Home

10-Minute Lagree Fitness Core Workout You Can Do At HomeI recently shot a workout with my girl Sarah for her YouTube channel, Sarah Fit, and wanted to share it here as well for anyone who isn’t a subscriber. I also have a question for you guys below so even if you’ve already seen the video, still scroll down!

10-Minute Lagree Fitness Core Workout You Can Do at Home

You’ll do each of the megaformer-inspired exercises for 60 seconds (just like in a Lagree Fitness class) and there are wrist breaks built in so that you’re not in a plank the entire time. You’ll need a pair of gliders, a dish towel, paper plates, or anything that will slide across the floor.

My favorite part of shooting this workout was getting to sit there talking while Sarah did all the hard work (LOL). Not because I’m lazy–it’s just so much easier to teach and explain exercises when I’m not also focusing on doing them. Sometimes I’ll finish shooting one of my workout videos, watch it back, and immediately think of a million cues and explanations I should have given. I loved being in full-on teacher mode here. 10-Minute Lagree Fitness Core Workout You Can Do At Home

Question for You

Now that I’m starting to get the hang of this whole YouTube thing, I want to make workout videos for older workouts in the archives. I’ll still post a new one each week, but maybe every other Thursday I’ll also republish an old post (#TBT) with a new video to accompany it. This is a great way for new readers to find the best older content they missed, and also an opportunity for long-time readers to try a workout that they might have skipped because it was unclear how to do a move from pictures alone.

So my question for you is: What workout(s) from the archives would you like to see in video form? My kettlebells are still in storage from moving so unfortunately a remake of kb workouts won’t be happening any time soon. Everything else is fair game! Leave a comment below or if you’d rather not, tweet me (@nicoleperr), comment on my latest Instagram (@nicoleperr) or send a carrier pigeon. 😉

If you haven’t already, be sure to subscribe to me (and Sarah!) on YouTube.

Enjoy the rest of your Tuesday!
