In general, the best form of exercise is something that you do regularly, so anything that inspires you to exercise more is good. One of my medical school professors liked to say "The best exercise for you is the best exercise for you," meaning that there is no one perfect form of exercise that is universal.
In general, I am not a huge fan of machines that are designed to target one body part, for several reasons. First, it is not possible to spot reduce fat in one region of the body, so machines tha

It's a great machine, the main drawback being that you need a large enough space to use one.
Amongst smaller gadgets, one that I really like is the BodyBlade. It's basically a stif
