can easily move us into the high intensity exercise zone above the 75 percent effort required to get some afterburn, but it's only for short bursts. This is not consistent, steady-state effort and does not generally burn as much energy as a good run on the treadmill, cycle or row machine at moderate pace. For example, here are the energy expenditure calculations for weights versus cardio for one hour of exercise from the NAT Nutritional Analysis Tools web site. I've based this on a 150 pound person (just under 70 kilograms).
- Running at 8 minutes a mile pace (5 min/km) -- burn 852 calories (kilocalories)
- Weight lifting, vigorous, free weights or machines -- burn 409 calories (kilocalories)
I’ve tried to line these activities up for effort so that the comparison is worthwhile. Whenever I check these numbers it astounds me because I run and I lift weights, and sometimes I feel much fresher after a run than going for it in the gym with sub-10 RM (repetition maximum) and three sets of ten exercises. Nevertheless, the numbers always come out the same with any reputable energy calculator. Sustained aerobics always spends about twice the energy of weight training in a comparable comparison. You can see from this why cardio sessions are important for fat loss.
