SINGLE-ARM DB CURL
- Take a dumbbell in one hand and let your arm fully extend. You should be able to flex your triceps in the bottom position.
- Keep good posture by holding your chest out, pinning your shoulders back, and switching your abs on. This will limit any swinging which may occur when you grow tired as the reps mount up.
- Keep your elbow tucked tightly to your side (like a T-Rex).
- Curl the weight up by squeezing your biceps HARD, controlling the force even on the way back down.
