A REVIEW ABOUT THE HEALTHY RATE OF WEIGHT GAIN DURING A NUTRITION & TRAINING PROGRAM

In the world of sports, the question often arises: how much lean weight can a teen athlete gain in a week? This issue is particularly relevant for young athletes who aim to maximize their performance while maintaining a healthy lifestyle. Here at Dawn Weatherwax’s Sports Nutrition Academy, we provide the necessary guidance to navigate this complex process.

Teen Male & Female Weight Gain
It’s important to understand that gaining lean weight is hard work and requires more than just eating protein and taking supplements. In fact, the process of gaining lean weight can be different for teen males and females. According to Dawn Weatherwax's Sports Nutrition Academy, a teen male athlete can typically gain between 1/2 to 1lb of muscle per week, while a teen female athlete can expect to gain between 1/4 to 1/2lb of muscle per week.
Gaining Lean Weight: Hard Work but Worth It

Gaining lean weight is hard work. Optimal results require more than just eating protein and taking supplements. Being quick, powerful, and lean are the goals. However, rest assured that the hard work will pay off in the end.

Plan and Test: Timing is Everything

Remember, each year builds onto another. You can't make up for lost time. It's always best to start early and keep a steady pace. The younger years are the perfect time to grow and gain lean weight. Having a healthy and competitive advantage early on sets the stage for future success.

💡 Just “eating a lot” isn’t enough—you need a plan + testing.
