Get ready—this one's a lung buster. We're starting off with two uphill runs at six minutes each, followed by speed work on the back end. Think you can handle it? Good. The focus here is twofold. First part, lungs. Second part, legs. In total, this training session is only 45 minutes, but in all honesty, it may feel longer.
