• →Pushes bicep up
• →Often neglected
• →Critical for size

Conclusion

Big arms come from consistent training, progressive overload, and balanced bicep/tricep development. Train them directly, prioritize form, and watch them grow.

Build the bicep peak. Carve the tricep horseshoe. Fill out those sleeves.

Training Note: Elbow health is critical. Warm up properly, use full range of motion, and never sacrifice form for weight.
