Start: Position two eight-pound kettlebells on the ground, the handle of each kettlebell laying flat on the ground. Place your palms on the tops of the kettlebells, arms extended and shoulder width apart, your legs fully extended behind you, your weight balanced up on the balls of your feet.
Execution: Slowly lower into a deep chest stretch, taking three seconds on the way down. Pause briefly at the bottom, then press your body back up in a controlled manner, again taking a full three seconds.
Benefits: This is an extreme stability exercise focusing on forearm strength, biceps, delts, triceps, pecs, lower back and abs. For an added challenge, substitute 6-8-pound rubber medicine balls for the kettlebells.
Use it: Perform three sets of 10 reps.
