So throughout my first two years of high school, I played baseball. Upon doing this, lifting weights was a requirement. Every practice we would lift for an hour. During this time, I put on about 10 lbs. of muscle, which really boosted my self-confidence. 10 lbs. seems so little, but when you only weigh 135 to begin with, it's a good step. But after that, I basically just got lazy as all hell and went back to being a scrawny kid again. So I've decided to get back into lifting, but making 20 lbs. my goal. Not 20 lbs. of pure muscle, per se. Just 20 lbs. more of weight. I'm 5'10" and 135, so I'm not exactly beefy. As of Monday, I will begin a 12 week regimen in the weight room as shown here: 12 Week Beginners Training Routine | Muscle & Strength It states two nonconsecutive days a week, but I'll be doing 3; Monday, Wednesday, Friday. Does anyone have some helpful tips aside from what's listed? I know I'll certainly have to decrease the soda and increase the water, but I generally eat pretty well. I love salads and chicken, and generally tend to eat about 4 meals including each per week. Actually, I eat chicken almost every day. Plus I'm straight edge, so no smoking or drinking has been, nor will be had, so I'm good on that. I'm also considering buying some Creatine to help with the mass. Any suggestions are helpful.
