B Strong Greatest HIITs 2017: Plank Crab Walk + Dynamax Push-Thru Core Challenge

Day 19! This exercise will improve you core strength, your shoulder stability AND your coordination. I highly recommend using the Dynamax ball over a rubber med ball so you don't bruise your knee ;-)

Here's the exercise:
- High Plank hold + Dynamax push-through (left arm pushes ball underneath torso & to right & vice versa)
- Do an oblique crunch to catch the ball with your knee
- Then do 2 "crab walks" over the ball so it's back on the side it began
- Perform movement, in the same direction, for 45-90sec
- Rest 15-30sec before performing back the other direction
- Complete a total of 3-5 sets in each direction

Did it take you long to get the hang of this exercise?! Tell me on IG/FB/TW @cassiebstrong!

B Strong,
