Swimming

Swimming provides a full-body, low-impact workout that burns 400–700 calories per hour for a 150-pound person, engaging every major muscle group against water resistance. A 2020 study revealed swimming can reduce joint pain 20% more than #3 Running, making it ideal for those with injuries. The hydrostatic pressure also enhances venous return, improving circulation and calorie burn by 10% compared to land-based cardio at the same heart rate. For gentle yet effective fat loss, swimming outperforms most alternatives.
