Exercise Safety Basics

General principles

• Start where you are. Choose a level you can control with good form, then progress gradually.
• Progress slowly. Increase load, reps, or difficulty a little at a time. Sudden big jumps raise injury risk.
• Prioritize form over weight. Controlled movement through a range you own beats heavier, sloppy reps.
• Warm up and include a mix of activity. National guidelines recommend regular aerobic activity plus muscle-strengthening on 2+ days per week for adults.

Normal effort vs. warning signs

Muscles working hard, breathing faster, and mild next-day muscle soreness are normal. The following are warning signs to stop and seek advice:

• Sharp, sudden, or joint pain (not muscle effort).
• Chest pain, dizziness, fainting, or unusual shortness of breath.
• Numbness, tingling, or weakness.
• Pain that persists or worsens after training.

Never train through sharp pain, and never ignore pain hoping it will pass.

Scope of practice: when to refer

A personal trainer teaches exercise and healthy movement. A trainer does not diagnose injuries, treat disease, prescribe rehabilitation, or give medical or detailed nutrition prescriptions. Refer to the right professional when:

• There is pain, injury, or a suspected medical condition → physician or physical therapist.
• Specific medical nutrition needs arise → registered dietitian.
• Symptoms are red flags (chest pain, fainting, severe or spreading pain) → urgent medical care.

Knowing the edge of your scope is part of being a good, safe trainer.
