Planks
Helps develop your abs.
Crunches
This targets your upper abs. I recommend
you also do 4 sets of your max or start count
and do 20 reps when you begin to feel the
burn.
Jack knives
You work your side and lower abs. I recommend you also do 4 sets of your max or start
count and do 20 reps when you begin to feel
the burn.
