Safety First: Managing Training Risks
Strength training can be a great activity for kids when done carefully. With the right safety measures, parents and trainers can help create a space that reduces the chance of injuries while encouraging healthy growth.
Preventing Common Training Injuries
Avoiding injuries starts with good supervision, proper technique, and a well-thought-out plan. Here are some important steps to keep in mind:
- Use equipment that fits the child's size and ensure there’s enough open space.
- Allow time for muscles to recover and rebuild after workouts.
- Gradually increase weights only when proper form is consistently maintained.
- Keep sessions short and focused, prioritizing quality over quantity.
- Ensure a qualified instructor is always present for supervision.
Pay special attention to form to prevent issues like:
- Improper breathing: Encourage steady, even breaths during exercises.
- Rushed movements: Focus on slow, controlled motions.
- Overloading: Start with bodyweight exercises before adding weights.
- Poor posture: Maintain a neutral spine and proper alignment during movements.
A thorough evaluation is key to ensuring kids are ready to progress safely.
Health Checks Before Starting
Before kids begin strength training, a full health evaluation is essential. This includes:
- Medical ClearanceA physical exam to check growth plate development, joint stability, past injuries, and overall physical readiness.
- Fitness AssessmentBasic tests to evaluate strength, movement patterns, balance, coordination, and core stability.
- Individual ReadinessAn assessment of the child’s ability to follow instructions, their maturity, motivation, and focus.
At Train with Dave, every participant undergoes this detailed screening process. Regular check-ins ensure the program evolves as kids grow, keeping training safe and effective.

Strength training during pre-adolescence lays the groundwork for long-term physical well-being:
- Better bone strength: Resistance exercises encourage bone growth.
