I used to weigh 212lbs at 5 '8, 14 years, literally like no muscle, just a lame fat kid. Then at 14, I was full of being a lame fat kid and wanted to be cool for a change. After about 6 months of stupidly low caloric intake (800-1500 calories and fasting up to 3 days) and lifting 3-5 days a week with no set goals for lifts, I got down to 145 lbs. All I did was stupid isolation work, no squats, deads, presses, nothing. About 3 months ago I really started focusing on compound movements. In the last month, my numbers went up as follows: 275 1rm to 295 3rm (deadlift), 115 5x5 to 140 5x5 (bench), 135 5x5 to 225 3x5 (squat), and 65 5x5 to 105 5x5 (ohp). I try to lift heavier weight every workout on my compounds or higher reps with previous weight lifted. Current stats: 5 '11, 15 years, 148-151lbs. Currently eating 3500-4000 calories a day.
Now that I have given a bit of a background, my problem is screwed up posture. Shoulders are always rolled forward and scapula just protrudes out if I’m relaxed. Just today found out how big of a problem my screwed up posture and lack of mobility will cause me in the future (and honestly now as well, being a hunchback isn’t something I dream about).
Question: Should I start from the bottom (bar only weight) on my compounds till I fix my posture with various stretches and exercises (high rep rows, band pull aparts, DB pullovers, etc…), and build back up to my current lifts, or should I keep lifting my current numbers and work on my posture simultaneously?
Thanks a lot, T-dawgs.
