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.
8 Exercises That Work Your Arms and Legs at the Same Time. To get you out of the gym faster. Some people separate upper- and lower-body workouts to perform on different days of the week. This way, you can rest one set of muscles while you exercise another and without skipping a single day at the gym. If you don't work out quite so regularly or want to feel the burn everywhere every time you strap on a sports bra, focus on compound exercises that engage multiple muscle groups at once.
