5. You’ll Burn More Calories
You may burn more calories during your 1-hour cardio class than you would lifting weights for an hour, but a study published in The Journal of Strength and Conditioning Research found that women who did weight training burned an average of 100 more calories during the 24 hours after their training session ended.
And the effect is magnified when you increase the weight, as explained in a study in the journal Medicine & Science in Sports & Exercise. Women who lifted more weight for fewer reps (85 percent of their max load for 8 reps) burned nearly twice as many calories during the two hours after their workout than when they did more reps with a lighter weight (45 percent of their max load for 15 reps).
