Fitness & Training Guidelines for Youth: FITT-VP and Safety Limits
Fitness & Training Guidelines for Youth tests the specific prescriptions and safety limits you would use to program for a young client, drawn from consensus youth physical activity and resistance-training position stands.
Daily activity baseline
Youth should accumulate at least 60 minutes of moderate-to-vigorous aerobic activity daily, with vigorous activity and muscle- and bone-strengthening activities on at least 3 days per week. That is the floor for health, not the training program itself.
Resistance training parameters
- Frequency: 2-3 nonconsecutive days per week
- Volume: 1-3 sets of 8-15 repetitions; beginners start with a single set
- Intensity: moderate load that permits clean technique (roughly RPE 5-7)
- Progression: about a 5-10% load increase once the top of the rep range is completed with good form
- Emphasis on multi-joint movements, bodyweight mastery first, and qualified supervision
Maximal (1RM) testing is not recommended for untrained youth; use rep targets or estimated loads instead.
Other modalities
Plyometrics: begin with low-intensity jumps, 1-2 sessions per week, roughly 80-100 foot contacts for beginners, on nonconsecutive days. Speed and agility: efforts under about 10 seconds with full recovery. Flexibility: 2-3 days per week, 15-30 second holds, 2-4 reps per muscle group.
Session design
Dynamic warm-up, skill and strength work while the client is fresh, then conditioning, then cool-down. Keep it playful: games can deliver conditioning without turning the session into adult cardio.
Worked example
A 13-year-old beginner with no training history: two full-body sessions weekly, 4-6 exercises, 1-2 sets of 10-15 reps at bodyweight or light external load, RPE 5-6, a dynamic warm-up, and a hop or jump-rope progression of 40-60 contacts. Load rises only after 12-15 clean reps across all sets.
Traps
Applying adult hypertrophy prescriptions (3-4 sets of 6-12 at high intensity); training to failure; high-intensity plyometrics before a strength base; scheduling resistance sessions on consecutive days; using 220 minus age to set intensity zones.
