About 8 ounces (.25l) every 15-20 minutes is optimal for feeling and performing at your best. Unlike other forms of exercise like lifting weights, which is often done in short, intense bursts, cardiovascular training forces you to expend more energy for longer periods of time.

Schedule your workouts for the late afternoon hours when temperatures are highest. Make sure you’re properly hydrated before you get moving, especially on scorching summer days. They’re not called “sweats” for nothing. Ditch the revealing, ventilated materials like neoprene for future workouts and go with a basic close-fitting cotton ensemble instead. Insulated clothing keeps the heat your body releases during exercise close to the skin, which can quickly induce perspiration.  Look for “sauna suits” made from PVC and other waterproof materials.
