Grab a matching pair. Most gyms have 5-lb increments — round to closest available pair.

Coach J’s Note“Dumbbells build stabilizer muscles that barbells miss. Each arm works independently — no hiding a weak side. Use DBs for accessory work, unilateral strength, and injury prevention.”

Dumbbell Training for Track Athletes

Why dumbbells? They force each side to work independently, exposing and correcting imbalances. Sprinters especially benefit from single-arm and single-leg DB work.

Rounding: Most gyms have 5-lb increments. Going slightly lighter with better form beats going heavier with bad form.

Per hand vs total: “I bench 75s” means 75 lbs each hand (150 total). This calculator shows per-hand weight — that’s what you grab off the rack.
