wanna build up your stomach eh? do the 15 minute abs work out every second day untill you build up to be able to do it everyday.
just do the following
-situps to the left for 1 minute
-situps to the right for 1 minute
-leg raises for 1 minute
-lay on your back and mack the motion of climbing stairs with you legs for 1 minute
-repeat theys for excersis 3 times one after another till you get to 12 minutes(keep in mind that you must not stop just keep going no matter how much it hurts)
-for one more minute do normal situps
-now for the last 2 minutes either get in a push up position with your elbows on the ground and hold you self there or do the para shout potition which is much harder and hold that for 2 minutes.
(parachute postion is when u lay on your back and lift up both your upper body and legs a few inches off the ground at the same time)
thats what ive been doing and body shots can't hurt me
enjoy
