Hey. Im 17 and I just made the school rugby team. I am pretty small around 5'8', 145 pounds. I recently got a membership to the gym where i go with my friend. I really want to find out how to put on muscle fast without overtraining. Anything you could tell me would be helpful as i never really worked out before in my life. I don't know how often to go( more than less prefferably) and how to maximize my workouts. Any tips are appreciated.

Hey! Welcome to the forums. For starters please take a look at this thread:

you need to be strong for rugby - do you just want stength or do you want size as well?
Find an online calculator of your calorie maintenance line and then eat 300-500 calories more than that a day-bulking. This will provide your body with enough excess energy to make muscle. Also, about 1-1.5 grams of protein/pound of body weight per day.

If you just want strength maybe a 3-6 rep range. If you want a bit of both maybe 5 sets of 5 reps (5x5). Remeber, keep to compound workouts for muscle gains. Use mainly free weights, often machine exercises aren't very good. ( I know, a generalisation.)

Look on sites with videos of all exercises e.g. criticalbench.com or coopersguns.com

You will not be able to gain size immediatley. Be patient, it takes some time and you will get better at working out and eating big. Carry a piece of paper around with you and write the calories and protein from each meal. I go to school so can't take the suggested 5-6 meals a day. Just eat big breakfast, eat lunch and maybe bring a sports bar or two to school with you then have an early dinner then maybe another one later on.

I suggest probably a full body workout (fbw) 3-4 times a week with one/two days rest inbetween. If you are struggling for calories or protein I suggest milk - its great for both.

I would suggest starting with lighter weights and concentrating on making sure you have correct form before lifting heavier.

Thanks alot guys for all your help, i was going everyday before but thats before i learnt that that is not the best way, would it be better to do more weight less reps or less weight more reps

Well more weight and less reps is more for achieving strength and less weight and more reps is more for achieving size.. You should do around 8 - 12 reps. That will give you both strength and size over time.
