Frequently asked questions
Do I need to gain weight to play baseball?+
Playable strength matters more than scale weight. If you are under the 25th percentile and struggling with velocity, adding lean mass usually helps.
How fast should a young athlete gain weight?+
About 0.5-1 pound per week of mostly lean mass is a realistic, healthy pace for a growing high school athlete.
