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.
You're muscles don't need to be 100% ready to work them hard. You're muscles don't know how much weight you're doing nor do they know how many reps you're doing. All your muscles know is time under tension, your still under tension when you work them on chest day and any additional work will still stimulate the group.
