If you want a body that works as great as it looks (and vice versa), this total-body routine is the answer. You'll not only hit max muscle, which ups your metabolism, but also strengthen your core and hone your balance to protect injury-prone spots. Tackle the moves from WH columnist Amy Dixon, an exercise physiologist and group fitness manager for Equinox in Santa Monica, California, two ­nonconsecutive days a week and you'll be a well-rounded (not round!) fitness specimen.
For a head-to-toe hard body, do these moves twice a week. Where applicable, opt for a weight at which you can barely eke out the last rep of your final set with perfect form.
