Cardio & Endurance
Football isn't distance running — it's repeated short bursts with brief recovery. The goal is to build the kind of endurance that keeps your kid sharp in the fourth quarter.
Football-Specific Cardio
A football play lasts 4–7 seconds. Then there's 25–40 seconds of rest. Then another burst. That pattern repeats 60–80 times in a game. Training should mirror this — interval work beats long jogs for football conditioning.
Interval Sprint Workout (15 Minutes)
- 3-minute light jog warm-up
- Sprint 40 yards at 80–90% effort
- Walk back to the start line (this is the rest)
- Repeat 10 times
- 3-minute cool-down jog
Tempo Runs (20 Minutes)
- Run 100 yards at 70% speed (not sprinting, not jogging — a controlled run)
- Walk the end zone (10 yards) to recover
- Run 100 yards back
- Repeat for 15 minutes
- This builds the aerobic base that supports everything else
Play-Simulation Intervals (10 Minutes)
- Sprint 10 yards
- Rest 25 seconds (stand, walk in place — simulate being in the huddle)
- Sprint 10 yards
- Rest 25 seconds
- Do 15 reps — this mirrors an actual football drive
Building an Aerobic Base
Intervals are great, but your kid also needs a basic aerobic foundation. If they can't jog for 15 minutes straight, start there before adding intensity.
Week-by-Week Base Building
| Week | Goal | Frequency |
|---|---|---|
| 1–2 | Jog 10 minutes without stopping | 3x per week |
| 3–4 | Jog 15 minutes, add 2 sprints at the end | 3x per week |
| 5–6 | Jog 15 min + 6 interval sprints | 3–4x per week |
| 7–8 | Switch to full interval workouts | 3–4x per week |
Heat Conditioning
Football season starts in the heat. Preparing for hot-weather performance is critical — especially for kids in pads.
- Acclimatize gradually. The first week of hot-weather training should be 50–60% intensity. Build up over 10–14 days.
- Hydrate aggressively. Start drinking water the day before. Add electrolytes on hot days.
- Train in the heat (safely). Short sessions in warm weather help the body adapt. Never push through heat illness symptoms.
- Know the danger signs: dizziness, nausea, confusion, stopping sweating, or cramping that doesn't resolve. Stop immediately if any of these appear.
Recovery Between Efforts
Teaching your kid to recover efficiently between plays is as important as fitness. During rest periods:
- Breathe through the nose, out through the mouth. This slows the heart rate faster than panting.
- Hands on knees or stand tall — both work. Whatever helps them breathe deepest.
- Stay mentally engaged. Use the huddle time to think about the next play, not how tired they are.
