build muscle, creatine
My husband likes to lift weights and build muscle, and I know it takes a lot of hard work and dedication.  Taking muscle supplements, herbal supplements and eating well can be very helpful.  One muscle supplement called Creatine is said to help people to build muscle, and you can buy it in natural food stores online.  Your body makes creatine and it's found in meat and fish as well, it's involved in muscle growth. 

It's a good idea to eat a healthy diet as well as drinking a lot of water when you are trying to build muscle.  Most supplements used to build muscle I have seen also tell you in the instructions to drink as much water as possible while taking them, for best results.  When trying to build muscle, also getting plenty of rest is a good idea.

Trying to build muscle is not easy, you have to be focused and work hard, but it can be done.  My husband is a living example of that, he's been working to build muscle for a few years and he really enjoys doing it too.
