Some of us enjoy going to the gym and have no problem spending at least 50 minutes exercising. There are others who have made weight training a part of their lives simply because they feel it is necessary for a healthy living plan. For some who find it difficult allotting time for the gym it may not be necessary to spend as many minutes as you think. A study done at Lehman College in the Bronx and reported in the August issue of Medicine & Science in Sports and Exercise offers some new information. The study involved 34 fit young men. All had experience in resistance training. They were divided into 3 groups. The first group spent 70 min. completing 5 reps of each exercise. The second group spent 40 min. finishing 3 sets and the last group spent 13 brisk minutes performing each exercise quickly and to the point of failure (physically unable to perform another repetition). After 8 weeks and 3 sessions a week all were tested. All three groups had gained the same amount of strength. The difference was in muscle size. Whatever your goal is, gaining muscle or just supporting the health of your bones, resistance training can have significant benefits regardless of the amount of time you spend at the gym.
