What It Is
Lap swimming with alternating arm strokes, a no-impact workout that builds endurance and is easy on sore joints.
How to Do It
Swim at a pace where you could talk in short sentences at the wall. Reach each arm forward and pull it back to your hip. Roll your head to the side to breathe. Rest at the wall when you need to.
Skill Level
Intermediate. Free-weight lifts, single-leg balance under load, or near-bodyweight strength moves. Form matters.
Type
Cardio. Raises your heart rate to build endurance and heart health.
Engagement
Unilateral (Alternating). Each rep alternates between sides.
