Plié jump squat
Targets: Abs, quads, glutes and inner thighs
Stand with toes pointed out. Interlace fingers in front of chest and lower into a deep plié squat. Explosively jump up, keeping toes pointed. Land softly back into a deep plié. Do 10 to 15 reps.
Perfect your form: Avoid bending knees beyond toes.
Dial it down: Skip the jump; focus on the squat.
Amp it up: Hold squat for 3 to 5 seconds before jumping.
