So how often should you train to build muscle? It's a good question. Many people find that they're training too hard to begin, and they get sore mucles. Others find that they're not training enough. This can be because of time restraints, or injury, or just lack of motivation.
Here's the ideal solution. If you're training to gain muscle mass, you only need to train 3 times a week, for about 45-60 minutes. That's it. Surprised? I was when I started. The reason why is because most of the muscle growth occurs AFTER the training session. The actual weight lifting session only needs to be short, but intense.
The whole reason you're lifting weights is to stimulate your muscles to grow. That's all. When you train hard, your body will grow and repair itself when your sleeping, working and geting out in the world. No need to spend hours in the gym, just 3 hours a week really. So you can get on with your life with no worries.
So work hard while you're in the gym, 3 days a week for about 45 minutes, lift heavy weights and you'll have plenty of time to enjoy your social life and show off your new muscles. Go hang out at the pool! You've now got plenty of time to hang out with your friends, and get your work done.
When you train like this you'll get big fairly quickly. Give it a try for about 3 months and your friends will start to comment on your massive gains. Don't worry too much about supplements. Just eat good wholesome food and plenty of protein. Make sure you're doing the lifts correctly when you train. Sometimes it's a good idea to consult a professional trainer before you start just so you know exactly how it's done. Last thing you want to do is get an injury just when you start out. Keep it real!
