The Fourteen-Year-Old Who Wants a Fifth Training Day
A 14-year-old female volleyball player currently trains three times per week with you for 60 minutes and has two 90-minute team practices. She asks to add a fifth strength session because she wants to “get stronger for club tryouts.” Over the past three weeks, she has reported feeling tired in warm-ups, her jump height looks lower late in sessions, and she says she is sleeping about 6.5 hours on school nights. Her parents mention that her grades have slipped slightly and that she is eating “whatever is quick.” She has no pain, but she is frustrated that her squat weight has not increased. She wants a hard program with more volume and less rest.
1. Should you add the fifth strength day? Explain your reasoning using recovery and readiness signals.
Read the worked answer
I would not add a fifth strength day now. She already has five weekly training exposures when the three strength sessions and two team practices are combined, plus school demands. The signs point to inadequate recovery rather than inadequate training volume: fatigue in warm-ups, lower jump height late in sessions, about 6.5 hours of sleep, and a slight grade decline. Adding more volume and reducing rest would increase fatigue without giving her the adaptation she wants. Her frustration about the squat weight is understandable, but strength gain depends on recovery as well as stimulus. I would explain that more is not automatically better and that we need to protect sleep and school first. If she wants extra work, I would add a short, low-intensity movement or mobility session only after sleep improves and we confirm she is recovering. I would also check whether her technique or consistency, rather than volume, is limiting her squat progress.
2. How would you adjust her current three sessions and monitor her response over the next four weeks?
Read the worked answer
I would keep three sessions but reduce unnecessary volume, especially high-impact jumping and repeated high-rep sets. I would use a simple readiness check at the start of each session, such as sleep, soreness, and energy on a 1–5 scale, and adjust the day's load accordingly. I would use reps in reserve or a moderate RPE target, such as 6–7 out of 10, rather than pushing every set near failure. I would prioritize a few compound patterns, such as a squat or split squat, a hinge, a push, a pull, and trunk work, with 2–3 sets each. I would keep one short power block with low volume and full rest, such as 3 sets of 3 low-level jumps, rather than high-volume plyometrics. I would track jump height, squat load, and her reported energy weekly. If energy does not improve after two to three weeks, I would reduce volume further and discuss sleep and fueling with her and her parents.
3. What would you say to her and her parents about sleep, fueling, and the goal of getting stronger?

I would connect the goal directly to the behaviors: “You want to jump higher and squat more, and those improvements happen when training and recovery are balanced.” I would explain that 6.5 hours of sleep on school nights is likely below what a 14-year-old athlete needs, and that low energy and late-session performance drops are clues. I would avoid prescribing a specific calorie target or a diet. Instead, I would suggest practical fueling habits, such as eating a mixed meal or snack before and after training and keeping quick options like yogurt, fruit, and sandwiches available. I would involve the parents by asking what the family can realistically do. I would also set a clear training goal with her, such as improving squat technique and consistency for four weeks, rather than chasing a number. If fatigue or grades continue to worsen, I would recommend a conversation with her pediatrician.
