11. One-arm kettlebell floor press Targets: Chest, arms, core Level: Intermediate How to: Lie on the ground with your legs straight out. (Nope, it’s not time for savasana!) Grab a kettlebell by your side and, with the palm facing in, press the weight straight up while rotating the wrist (so the palms face the feet). Bring the kettlebell back down to the starting position, and repeat for 6-8 reps.
