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.
For your lower body, warm up with squats. For your upper body, use a combination of bench presses and rows. Start with a weight that you figure you can lift 15 to 20 times, but perform only six repetitions. Wait 30 seconds, increase the weight to an amount you can lift just 10 to 15 times, and do four repetitions.
