Croc Walk With Sliders

If you don't have a pair of sliders, use two hand towels on smooth surfaces, or paper plates on carpet. If you don't have enough space to walk your plank, just do plank ups with sliders. If you don't have sliders, towels, or paper plates, just do mountain climbers [13].

Single Arm Overhead Squat
