Community & Expert Q&A
Question: Should I do strength training on the same day as running?
For beginners, alternating days (e.g., Run Mon/Wed/Sat, Strength Tue/Thu) gives your legs fresh recovery for each session.
Question: Why do I get a side stitch when running?
Usually running too fast too soon after a heavy meal or shallow chest breathing. Slow to a walk, exhale fully as your opposite foot strikes, and wait two hours after big meals.
