7-Minute Workout for Triathletes

Written by
Whether you're traveling, on vacation, looking to spend more time with family and friends or just don't feel like a long, extensive workout, you can still get your sweat on with a few simple exercises done in a circuit or high-intensity intervals.

High-intensity activity in circuit training can simulate strength gains in the body's major muscles groups, as well as improve cardiovascular endurance, according to an American College of Sports Medicine article by Chris Jordan. This, in turn, will help triathletes race at optimal levels for longer, making long-distance triathlons easier.

To get the most out of the workout, work each exercise for 30 seconds before moving to the next. After one round, you can either take a 30-second break and complete another round or be finished.
