Now I'm here to introduce to you another two shortcuts to shape-up your body fitness.
Skipping the last three reps
Bad idea
> The final reps of a move are where the magic happens. "You have to stress your muscles if you want them to change, and that occurs in those last few reps:' says Holland. Your last reps should be tough to finish but not so difficult that you have to compromise your forYm .lf your form starts to suffer early in the set, switch to a lower 17 weight so you won't have to skip the last reps-or hurt yourself trying to push through them.
Resting longer than the prescribed time during a circrut Go for it
> Many circuits call for short rests-usually 30 to 60 seconds-to keep your heart rate high enough to produce a cardio benefit (read: calorie burn). But ifyou're really struggling after a tough set, tack on an extra 30 seconds of rest, says Rebecca Stephenson, a board-certified women's health specialist in physical therapy at Harvard's Brigham and Women's Hospital. It will give you (and your muscles) enough of a breather to complete the next set with perfect form without compromising your calorie burn.
