just follow the following routine on alternate days.(MONDAY, WEDNESDAY and FRIDAY)
Abs exercises are more effective if u perform fast .
1. Calves on Bench Crunches 3 sets of 20-30 reps
2. Leg Raises 3 sets of 20-30 reps
If you can't perform 20 reps for any of the above exercises do the maximum you can .
IMPORTANT:-
Just making abs muscle doesn't mean everything is done.
There are many people who do abs exercises for 1 year or more , but they don't have a visible six pack.
You need to remove fat from your belly to make the six pack visible,
REMEMBER:-
Abs exercises do not remove fat from your belly.
You can remove fat from all over the body and never from a single part.
To remove fat you can do a fat burning workout on Other days (TUESDAY, THURSDAY and SATURDAY)
and the Most Important thing is DIET, you can't compromise
