Bottle Weighted Alternate Biceps Curl

Cómo hacer el Bottle Weighted Alternate Biceps Curl

1. 1Fill two water bottles to a similar weight and hold one in each hand at your sides, palms facing forward.
2. 2Stand tall with your feet about shoulder-width apart, knees soft, and your core braced.
3. 3Pin both upper arms against your sides and keep your wrists straight throughout the movement.
4. 4Curl the bottle in your right hand up toward your shoulder by bending only at the elbow, squeezing your biceps at the top.
5. 5Lower the right bottle under control back to your side until your arm is fully extended.
6. 6Repeat the same curl with your left arm while the right arm rests at your side.
7. 7Continue alternating arms for your target number of reps, keeping each rep slow and controlled.
8. 8Finish by lowering both bottles to your sides and setting them down safely.

Consejos de técnica

• Keep your elbows fixed at your sides so the biceps do the work instead of swinging from the shoulders.
• Lower each bottle slowly, taking about two to three seconds on the way down to keep tension on the biceps.
• Fill both bottles to the same level so each arm trains against an equal load.
• If the bottles feel too light, add weight by using larger bottles or filling them with sand instead of water.

Errores comunes

• Swinging the body or using momentum to lift the bottle, which shifts the work off the biceps and reduces the effect of each rep.
• Letting the elbows drift forward or flare out, which turns the curl into a shoulder movement and loses biceps tension.
• Bending the wrists backward under the load, which strains the wrist and forearm instead of loading the biceps.
• Dropping the bottle quickly on the way down, which skips the lowering phase where much of the muscle-building stimulus comes from.
