Iso-Hold Squat

Put the dumbbells on the floor; this move is done without weights. Stand with feet spaced a little wider than your shoulders. Now bend your knees and sit your butt back into a squat. Instead of pushing up out of the squat, stay there with thighs parallel to the floor for 30 seconds.  If you can’t hold for 30 complete seconds, go as long as you can, stand and shake it out and get back into the squat. Do this as many times as it takes to complete 30 seconds total. Rest for 20 seconds.
