🔥 BURN BYTES WOD #013 — CONCENTRIC POWER HOUR MINI! 🔥
💪 IT’S FITNESS FRIDAY!
New workout. New fitness term. And today, we’re learning what actually happens when your muscles produce movement!
📚 TODAY’S FITNESS TERM: CONCENTRIC CONTRACTION
Ever wonder what’s happening to your muscles when you lift a dumbbell?
A concentric contraction occurs when a muscle shortens while producing force.
💡 Think about a biceps curl:
⬆️ CONCENTRIC: Your biceps shorten as you curl the weight upward.
⬇️ ECCENTRIC: Your biceps lengthen under tension as you lower the weight.
Both phases are important for developing strength and muscular control!

1️⃣ 12 Dumbbell Biceps Curls
