Instructions
Ab Crunch Machine
Select a light resistance and sit down on the ab machine placing your feet under the pads provided and grabbing the top handles. Your arms should be bent at a 90 degree angle as you rest the triceps on the pads provided. This will be your starting position.
At the same time, begin to lift the legs up as you crunch your upper torso. Breathe out as you perform this movement. Tip: Be sure to use a slow and controlled motion. Concentrate on using your abs to move the weight while relaxing your legs and feet.
After a second pause, slowly return to the starting position as you breathe in.
Repeat the movement for the prescribed amount of repetitions.
Butt-Ups
Begin a pushup position but with your elbows on the ground and resting on your forearms. Your arms should be bent at a 90 degree angle.
Arch your back slightly out rather than keeping your back completely straight.
Raise your glutes toward the ceiling, squeezing your abs tightly to close the distance between your ribcage and hips. The end result will be that you'll end up in a high bridge position. Exhale as you perform this portion of the movement.
Lower back down slowly to your starting position as you breathe in. Tip: Don't let your back sag downwards.
Repeat for the recommended amount of repetitions.
Verdict
Both exercises target the abdominals. Ab Crunch Machine is a intermediate exercise using machine, while Butt-Ups is beginner and uses bodyweight. Choose Butt-Ups if you're looking for a more accessible option, or Ab Crunch Machine for a greater challenge. Butt-Ups is a compound movement working multiple joints, making it better for overall strength. Ab Crunch Machine isolates the target muscle for focused development.
