I glanced at the aerobics room at the gym today while doing cardiovascular work and saw a trampoline aerobics class. I loved all of the variety of exercises you can do on the trampoline. It is another way to get off the plateau, and can be used for interval training.
Abdominal exercises that can be done on a trampoline include crunches and leg lifts.
Crunches for upper abdominal muscles:
Lie down on the trampoline with your gluteus maximus on the edge of the inner circular part of the trampoline. Keep your feet flat on the floor, about hip-width apart. Put your hands behind your head with your elbows facing out, and proceed with abdominal crunches according to the first abdominal muscle blog. Keep your neck straight. Exhale when you come up and inhale coming down, up to an inch or two above the trampoline. Do five sets of ten repetitions.
Legs lifts for lower abdominal muscles:
Lie down in the same way. You can hold on to the sides of the trampoline for support. Straighten your legs without locking your knees. Lift your legs to about 90 degrees. Exhale when you lift your legs, and inhale when you lower them. Do five sets of ten repetitions.
