Resistance training that you can try at home

How much strength training is enough to build muscles and garner some health benefits? Kent Adams, director of the exercise physiology lab at Cal State Monterey Bay, says most healthy people can follow the basic guidelines from the American College of Sports Medicine, which recommends doing eight to 12 repetitions of eight to 10 strength-training exercises twice a week. (That's in addition to doing moderately intense cardio workouts for 30 minutes a day, five days a week.)
