15 workout upgrades for better results
Instead of: treadmill warm-ups
Upgrade to: medicine ball
Wood Chop Instead of doing a warm up that targets only legs, the wood chop targets the upper body and core as well.
Stand with feet slightly wider than shoulder width apart and hold onto a light-to-medium medicine ball (five to six pounds). Bend knees and hips, dropping into a squat as you bring the ball down to touch your left foot, shin or knee, depending on your level of flexibility. Rise up out of the squat as you simultaneously rotate and raise the ball up and across your right side, as if throwing it over your right shoulder.
Do two sets of 10 on alternating sides...
