Whether you’re deep into your marathon training or you’re just lacing back up for fall, now’s the time to get strong for the miles ahead. Your core — the engine for your extremities — is the best place to start. When it comes to core work, avoid crunches, which simply reinforce the flopped-forward posture you’ve been cultivating all day long while sitting. Instead, opt for moves that not only activate your core from the inside out, but also build total body strength and increase stability in key areas like your hips and upper back.
