No painful crunches on the floor - stand up and crush that core!
No hurting your back doing awkward, neck-pulling crunches with this one! These dynamic movements are done standing and work your obliques on the side, as well as upper, middle, and lower abs, and your legs get involved as well!
Plié squat with toes turned out, knee to elbow and repeat on the other side, then crunch upper body and reach elbows towards your knees in front (4x).
Go for 1 minute, rest 10 seconds, and repeat 3 rounds! Stronger core in 3 and a half minutes.
