Body By Rings (FitnessFAQs)

The pick if you own a pair of rings and want size as well as strength. It needs nothing but the rings, runs four days a week at around an hour a session, and includes spreadsheet and PDF logs. The entry bar is the useful detail: FitnessFAQs says you are ready once you can do 10 pull-ups, 10 dips and 10 push-ups, so this is a second program rather than a first. Rings punish shaky dips and push-ups far more than a fixed bar, which is exactly why they build stabilizing strength, and why the readiness test is worth respecting.
