Work your arms and abs with this one move

More and more people are returning to the basics to help them achieve their desired level of fitness, as evidenced by the increased use of kettlebells, total-body workouts, and old school exercises.

After falling out of fashion for quite some time, pull-ups have made their way back into many workouts. This is most certainly a good thing, for this one movement targets many muscle groups at once. Another exercise that, because of the advent of ab machines, had fallen to the wayside for some, but has recently become popular again, is the hanging knee raise. This ab-blasting exercise mainly hits the upper and lower abdominals, but when performed while hanging from a pull-up bar (rather than stationed in a captain's chair), it also calls upon the core muscles to help stabilize the body.

Combine these two exercises into one and you get an advanced and highly effective move called the Pull-Up to Hanging Leg Raise (thankfully, the benefits of the exercise far outweigh the amount of creativity that went into naming it). To do it, grab a pull-up bar with your palms facing away from you. Pull yourself up until the upper part of your chest is as close to the bar as you can get it. While holding in that position, bend your legs and bring your knees up and in toward your chest. To finish, lower your legs and then lower your body to the starting position.
