When it comes to exercising, doing more with less effort is the way to go, whether you're trying to save time, energy, money or all of the above. You probably already know that you can break up those 30 minutes of exercise that experts recommend you get daily - 10 minutes here, 10 minutes there, another 10 and it's done. Another way to make strength training faster is to work more groups of muscles simultaneously. It's a movement called compound workouts, and it's helping people build strength, burn calories and get toned, tight muscles. Combining a large-muscle movement, like squats, with hand-held weight training, can pay off big fitness dividends. Try walking lunges while doing bicep curls or lifting dumbbells straight above the head as you step forward. Use a medicine ball to complete side-to-side lunges while holding the ball, or as you do a standard squat, bring the ball between your legs as you go down.
