Listen up, runners! You probably know you should do more than endless laps and intervals to stay at the top of your game and prevent injury. But how often are you mixing in a strength routine, yoga class, or spin session? (Yeah, that's what we thought.)
Luckily, running coach and Ironman Luke Lombardo has a fill-in-the-gaps solution: a bodyweight-only no-nonsense workout that helps build strength. You'll start with a sprint, then move into some classics go-tos for a full-body workout that lasts just 15 minutes. Try this outdoors or in a gym using a treadmill. Either will have you sweating in no time.
