Bring the knees in towards the chest and lift the shoulder blades off the floor without pulling on the neck.

do hanging ab exercises those are awsome!

These exercises are great! Thanks guys

I noticed when you are doing program for mass you need to eat everything to gain weight of course so then abs exercise is useless to do it ;/

Thanks for information about Abs exercises and I do agree with all of you guys.

Sone,
I call BS. Look you should do abs 2x a week min no matter if bulking, cutting, whatever. Hanging knee raises, Knee ins on a flat bench, incline crunches. Knee in laying down.

Hi hering2,
Best abs exercises I have found in my 2 years gym experience. Renegade dumbbell rows,
Front squats with barbell and
Mountain climbers on floor.

Besides these bicycle exercise, exercise ball crunch and vertical leg crunch exercises are also effective.

Incline situps with a weight plate, torso twists on incline with a weight plate, bicycles on a flat bench, hanging knee raises. That is my typical ab routine.

There are many core exercises you can do without any equipment, and there are also some simple products that you can use at home, such as a large exercise ball. Using the ball for crunches requires that you stabilize your torso while balanced on the ball and you end up using more muscles than when performing standard crunches..
