Water fitness uses the support and resistance of water for low-impact cardio, mobility, and strength endurance. It can be gentle enough for recovery or structured enough to become a meaningful conditioning session. The water makes impact low while resistance increases with movement speed.

Benefits
Water fitness provides low-impact cardio, mobility, and strength endurance with support from buoyancy and resistance from water. It is approachable for recovery-oriented or joint-friendly sessions.
What to watch out for
Low impact does not mean no load. Keep movements controlled, watch pool surfaces and entries, and scale speed or range if shoulders, hips, knees, or back feel irritated.
