Weightlifting Safety Tips

Proper Loading: Always load plates from heaviest to lightest, with larger plates closest to the collar. This provides better balance and stability.
Collar Usage: Always use collars or clips to secure plates on the barbell. This prevents plates from sliding during lifts.
Double Check: Verify your plate calculation before lifting. Count plates on both sides to confirm they match exactly.
Warm-up Sets: Start with lighter weights and gradually increase. Use this calculator for each progression in your workout.
Gym Etiquette: Re-rack weights after use and load/unload plates carefully to avoid damage to equipment and floors.
Progressive Overload: Increase weight gradually over time. Small increments (2.5-5 lbs) allow for sustainable strength gains.
