You must do multi-joint exercises as part of your workout routine. Each time I do resistance exercises I incorporate at least two or more multi-joint or compound movements. By doing this I am working more than one muscle at the same time and burning more calories while getting stronger.
Many fitness gurus recommend these types of movements and in fact Crossfitters practice them regularly when training for their competitions. I recommend that you start doing them as part of your training if you want to see better results faster.
The following article from MSN goes into more detail about doing compound exercises.
The Exercises That’ll Help You Get More Done In Less Time
Keep in mind that isolation moves aren’t a bad thing—if you’re trying to focus on developing one specific muscle, they can be great, says Tamir. (Think bodybuilders doing ultra-heavy bicep curls for arm gains.) However, if your goal is to gain more muscle mass all over, compound exercises are much more efficient.
Building lean muscle also helps increase the number of calories you burn at rest (your basal metabolic rate, or BMR), because muscle requires more energy for your body to maintain. So because compound exercises help build up that extra muscle mass, they can give your BMR an even bigger boost.
