Watch your back. And, while you're at it, your abs, glutes, thighs, and calves, too. Lots of guys whip through a few pullups and bench presses and call it a day, completely oblivious to the jelly roll hanging over the top of their shorts. Too much focus on your arms and chest -- a.k.a. your "vanity muscles" -- screams underdeveloped physique and hypertrophic ego. It's also unhealthy, warns MF fitness adviser Craig Ballantyne, C.S.C.S., especially for your shoulders. His suggestion for making your workout the most effective fat-burner possible? Perform supersets in noncompeting pairs, such as bench presses and squats, or shoulder presses and calf raises -- exercises that give those vain muscles time to recover while you complete the other half of the set.
