How long does it take for a fractured hand to heal so that i can lift weights again?

6 weeks: Hand fractures generally take six weeks to heal. I would avoid weight lifting until at least six weeks after your injury. Make sure you see an orthopaedic surgeon for a physical exam and x-rays to make sure your bone is healed before you return to weight lifting.

When the bone heals: Once there is radiographic evidence of bone healing your doc will tell you when it is safe to begin to increase your activities including lifting weights. Usually it will be with light weights until your strenth increases.
