Itâs important to exercise your abdominal muscles, but not necessarily every day. While ab exercises are one of the few workouts you can safely perform five or more times per week, itâs really not necessary and can actually have a negative impact in some cases. Thereâs a big difference between âcan youâ exercise your abs every day and âshould youâ work these muscles daily. For the average person, daily abdominal exercise isnât any healthier than working your abs one to three times per week.
Building Muscle. Ironically, training your muscles every day is one of the worst ways to build muscle. Muscles grow during the rest periods between sessions, says trainer and nutrition expert Damien Mase on the Muscle and Strength website. When you strength train, tiny tears form in the working muscles. Itâs when youâre not working out that your body repairs this temporary damage by pumping extra blood into the affected muscles. This results in new tissue growth and therefore bigger muscles.
