I used to think it was simply a matter of choice to strength train before or after cardio. Most often, my preference is to save the weights until after I have done my cardio. After 20 to 30 minutes of running, I am warm, sweaty, and ready to pump some iron, and I feel less likely to injure myself. It looks like the Journal For Strength and Conditioning Research has added another reason to hold off on weight training until the cardio workout is over. You burn more calories, especially after you have finished exercising, by placing strength training second in the activity lineup. Cardio burns calories consistently, and topping that off with the extended caloric burn of strength training increases the overall benefits to your metabolism.
How do you organize your workout? Do you usually do cardio first or last? Tell me in the comments section below.
