I heard that ab muscles are tiny and can be exercised everyday.
Is this true, or do we need to take 1 to 2 day break in-between, just like the other muscle groups, i.e. arms, shoulders, back, chest, glutes, thighs, legs ....
By the way, I do light-weight exercises at home, the types you'd find on Pinterest, and maximum dumbbell weight is 8 lbs
