I want to gain muscle weight. Do I eat protein before or after the work out?

After the workout is more vital. Protein helps the muscle rebuild after you have worked out. It is very vital to have protein when you sleep. This is where most muscle repair takes place. Look for a carb boost before you work out for energy if you feel weak during your workouts, protein won't help that.

Both. But don't over do it. Try increasing your workout reps and sets. Plus don't forget the rest of your body. Work it out, keep it clean, and stay away from drugs, alcohol, and tobacco. Don't even think of steroids. They will do more damage than your hockey game is worth.

Just eat regular food. Of course if you're exercising and growing big muscles, you'll have a bigger appetite, but you don't have to do anything unusual. The supplements cost money, but that's all they do.

it is better to take protein after your workout. You should also take glutamine with your protein shake. It will help your muscle recover faster.

Your coach could probably give you some advice on this, as well as checking out some fitness sites online.

Good luck with the hockey!

You would need to take in at least 140 grams of Protein, as you weigh 140 lbs. Take protein shake 1/2 hour after work out. Eat tons of chicken breasts.

After. Before it will weigh you down and make it uncomfortable to exercise. Also, the logic is you "replace the muscle you wore down through exercise."

only after, about 30 min after the workout
during the workout you have to get some creatine, and any kind of oxidants and energy drinks.

I'm not a guy but protein should be taken 3 times a day. As for your workout, most exercise programs tell you to exercise on an empty stomach or 2 hrs. after a meal.
