Quick 20 Minute Treadmills Circuit For Ya 🔥 Get in. Get to work. Get out. Few weeks ago I finished off my full body lift with this circuit to clock some extra miles in before the marathon I was training for. You don’t have to spend hours in the gym to get the results you’re looking for. Have a plan, work hard, and then go recover. Hope you enjoy. #treadmills #treadmillworkout #intervaltraining #fitness #athlete #marathontraining
