Not all supplements are equal when it comes to helping you build the muscles you need. Try to avoid any supplements that have heavier substances. Most professionals recommend using nothing stronger than a basic whey protein so that you don't cause any nasty side effects to your own body.
You need to always stretch your muscles before beginning any weight lifting exercises. You can prevent a lot of injuries by properly warming up. Also, by preventing injuries, you will be able to stick to your routine.
Remember that it is never a good idea to use the scale to determine your progress when you are trying to build muscle. If you find that your scale is increasing in numbers, remember that you just might be losing fat while gaining muscle. Since muscle weighs more than fat, this is a familiar site for many who are trying to do both at the same time. Gauge your results by what you see in the mirror rather than what you see on the scale.
If you have been working out for a while, though you feel like your muscles are not getting as big as you would like them to be, try to focus your workouts on your biggest muscles. Work more on your chest, legs and back. This will help to increase your protein synthesis, which will help your muscles to get larger.
Set short-term and long-term goals. While you should have an idea of what you want to look like eventually, you will only reach that goal by sticking to smaller goals. For instance, try doing just two more bicep curls in your next workout. If you hit a plateau, do not worry. This happens to everyone. Give it time, and you will see progress soon.
