Episode 196: What should your gymnast weigh?

Is your gymnast going through puberty and suddenly looking slower, less powerful, or less consistent in the gym?

Has a coach, pediatrician, or even your own worry made you wonder if your gymnast’s weight or changing body is the problem?

This is one of the most sensitive and misunderstood topics in gymnastics and when it’s handled the wrong way, it can cause serious harm to a gymnast’s relationship with food, body image, performance, and long-term health.

In this episode, Christina breaks down the difference between body weight and body composition, why puberty changes can impact gymnastics performance, and why focusing on the number on the scale is almost never the answer.

Because while it’s easy to assume that weight gain is the reason a gymnast is struggling, the real issue is often under-fueling, low strength, poor recovery, iron deficiency, or a strength and conditioning program that hasn’t adapted to their changing body.

This episode is a must-listen for parents of gymnasts navigating puberty, body changes, performance dips, coach comments, or confusion around growth charts and weight.

In this episode, we cover:

❗ Why gymnast weight is such a sensitive topic
❗ The difference between weight and body composition
❗ Why a number on the scale does not tell the full story
❗ Why BMI and body fat testing are not appropriate tools for young gymnasts
❗ How growth charts are used to evaluate healthy growth and development
❗ Why gymnast percentiles may increase after puberty — and why that isn’t automatically a problem
❗ How puberty changes a gymnast’s body, strength needs, and performance
❗ Why gymnasts should not be expected to look like their pre-puberty selves
❗ The role genetics play in body shape, muscle mass, and body composition
❗ Why comparing your gymnast to teammates or elite gymnasts can be harmful
❗ Why weighing young gymnasts can create anxiety, disordered eating, and performance issues
❗ How under-fueling can make performance worse and increase injury risk
❗ Why dieting or weight loss is rarely appropriate for adolescent gymnasts
❗ How coach comments about weight can lead to long-term harm
❗ Why fueling, strength training, and recovery need to be the focus instead
❗ When to seek help from a pediatric sports dietitian

Not every performance struggle is about weight.
Not every body change is a problem.
And not every gymnast needs to be smaller, leaner, or lighter to perform better.

In fact, for many gymnasts, the real answer is not eating less — it’s fueling more intentionally, building strength, supporting puberty, and helping their body adapt to the demands of the sport.

Your gymnast’s body is not something to fix.

It is something to support.
