5-Minute Ab Blaster AMRAP Workout

It's been a while since I've posted a quick 5-minute workout for you all.  I was short on time at the gym yesterday, so to get in a good ab burn I decided to do a quick AMRAP.  I modified it a bit for the blog here, but the main idea is the same.  Do as many rounds as you can during the 5 minutes, and try not to take any breaks between exercises for maximum ab work in minimal time.  The best part is this workout requires no equipment, so you can do it just about anywhere.  Ready to get started?

5-Minute Ab Blaster AMRAP

Set your timer for 5 minutes and get through as many rounds as you can, trying not to take any breaks between exercises.  Let's work those abs today!

30 Cross-Body Mountain Climbers - just like regular mountain climbers, but instead of bringing your knees to your chest straight on, cross them to the opposite side of your chest.  Each knee in counts as 1 rep.  Do 30 reps total, working quickly.  Trainer Tip: if the running is too much, slow it down to just stepping.

20 Hip Touch Planks - start in a low plank position (on your elbows), and rotate your hips to one side while lowering them to the floor.  Keep your abs engaged and legs as straight as you can throughout.  Return to start and immediately rotate to the opposite side.  Do 20 total (10 on each side).

10 Oblique Crunches (R + L) - lie on one side, keeping your bottom arm extended out on the floor and top arm bent with your hand behind your head.  From there, crunch up to the side so your elbow meets your knees.  Continue the crunches for 10 reps on one side, then switch to the other.  Trainer Tip: if you want to make it easier, crunch up using only your top leg instead of both.  Harder = keep legs straight and "V" up.

20 In & Outs - sit down on the floor, legs extended with hands by your sides, elbows on the ground, chest up.  Bring your chest and knees up to meet in the middle, keeping your hands planted as your elbows come off the floor.  Extend back out to starting position, keeping your feet hovered over the floor.  Do 20 reps.  

30 Supine Flutter Kicks - lie on your back (with hands under your lower back for support if needed).  Keep your chest raised and legs out straight, hovering over the floor.  Alternate fluttering them up and down (tiny movements) without touching the floor.  Keep fluttering your feet for 30 (fast) reps.

Repeat all exercises as many times as possible within 5 minutes.
