We all make mistakes. But when it comes to your workout, there are easy ways to fix muscle-building blunders. Tweak your workout with these small changes and start sculpting the body you want:
Run a lot? Chances are you’re hurting your ability to pack on muscle. Instead of jogging and activating your slow-twitch muscle fibers—which seem to shrink your upper body bulk—opt for fat-incinerating intervals.
Want that enviable crease from your hip to your groin? Define it by working your upper abs with 20 to 30 crunches first. This will limit their assistance when you start working your lower abs.
For more powerful trunks, ditch the leg extensions. They isolate your quads. Body-weight lunges, on the other hand, stabilize your abs, lower back, hips . . . you get the point.
And forget curls. Shore up surrounding muscles with a cutting-edge workout for sleeve-busting arms.
