On the road again? Try these four quick-and-easy workouts next time you’re forced inside.

Few triathletes can claim a perfect training cycle without work travel, family obligations, or inclement weather getting in the way. Instead of throwing away a few training days, approach your stuck-inside status with a strategic plan.

When athletes tell coach Julie Dunkle of Boulder, Colorado-based D3 Multisport that they can’t train during a business trip, her response is simple: “Can’t or won’t? I always make time to train, even if it’s 15 minutes—so it can be done,” she says. With limited time, the six-time Kona finisher suggests going hard and fast for short periods. For instance, if you only have 25 minutes for a treadmill session, divide it into a 5-minute warmup followed by 10×90 seconds max effort with 30-second walk breaks.

Coach Kyle Herrig of Arizona-based Triplex Training sees travel as a time to focus on building strength. “There’s no excuse to not get in some strength training while on the road,” he says. “Use your body weight and increase your reps or speed of movement to make the exercises challenging. I usually try to keep it simple and give our clients five to six exercises to do while traveling—something simple they can do anywhere.”
