An ideal cardio session should be around 45 minutes. If you lift weights before aerobic training, youâll only need 15-20 minutes of cardio. Youâll get the same benefits as you would do in 45 minutes without weight training.
75 minutes the max for lower or upper body workout plus cardio.and not every workout.i never heard of overtraining leading to depression.must be a new finding. As an older guy I need my recovery time. I spend 6 hours a week in the gym, over three days. I believe the key is the variety in your workout. Two hours of lifting, for example, would be counter- productive. I usually do about 40 minutes weight training, 5 minutes core training, 25 minutes cardio, 10 minutes abs and 15 minutes yoga-stretching.
