text: is crunching and pilates equivalent to jogging on the treadmill? is crunching and pilates giving the same ab reduction as jogging on treadmill?whats to do if i get joint pains whenever i do the treadmill?can i substitute it by doing crunches every good exercise program has components of stretching, cardio, and strength training.  you can accomplish the same on an elliptical that you would on a treadmill, but quicker and with low impact (easier on leg joints).  plus you'll also tone your upper body.  if you want to do crunches there's a safe and effective piece of fitness equipment called a hyperextension (roman chair).  it's great for improving obliques, abdominals, and back muscles.  you don't really say what you're trying to accomplish, so i made some assumptions.
