You have to have resistance to build muscles. Weights are a form of resistance.
So is gravity! So you can do pull ups, push ups, sit ups, crunches, and lunges to build up strength.
You can do what are called isometric exercises where you pit one muscle against another. Example place your hands together, one palm facing up the other down. Push hard and count to ten. Flip over your hands and repeat. Repeat as many times as desired.
Running, swimming and most Martial Arts will help build muscle tone and strength.
