I've been Paleo for over a year. Always athletic, weight never an issue. When I rediscovered road cycling 4 years ago I let my gym membership lapse but I've decided it is time to get some strength training back into my life.

There are two rows of overhead (still?) rings in the park near me and I've gone over there and swung ring to ring, etc. My question is: Is this enough? I can go down the row of eight rings and back without stopping and I do a bunch of pullups on a ring. Anything else I could do with them?
