Side effects and risks
Using weight machines improperly can cause back injury.
Who should be careful, and drug interactions
People who have trouble moving or balancing, or who worry exercise may not be safe, are told to check with a provider first. People who haven't exercised in a while are told to start slowly and talk to a provider about health concerns.

Questions to ask your doctor
- Is Exercise a sensible option for me, given my health and the medicines I take?
- Could Exercise interact with any medicine or supplement I already take?
- What side effects should I watch for, and when should I stop or call you?
- How would we tell whether it is helping, and when should we review it?
