Summary
Jeff Cavalier of AthLEAN-X introduces the “Bulletproof Your Body” series, a concept focused on building muscle while minimizing injury risk. In this first installment, he presents the “No Money” Curl, a bicep curl variation that incorporates shoulder external rotation to protect the shoulder joint while still developing the biceps. The exercise addresses the anatomical connection between the bicep and shoulder, making it a safer long-term training option.
Key Points
- Standard curls alone are insufficient for bulletproofing the biceps because they don’t account for the shoulder’s role in bicep function.
- The long head of the bicep tendon attaches at the shoulder joint, meaning elbow flexion also involves the shoulder — overworking the biceps inevitably stresses the shoulder.
- Most trainees develop internal shoulder rotation from overworking the chest, shoulders, and biceps while neglecting the rotator cuff, leading to poor posture and injury risk.
- Incorporating external rotation during curls directly combats this internal rotation pattern and helps keep the shoulder joint healthy.
- The “No Money” Curl gets its name from the starting position — hands turned outward at the sides, mimicking the gesture of showing empty hands.
- The series plans to address multiple body parts including knees, hips, and ankles, noting that dysfunction lower in the kinetic chain can affect the back and even the shoulders.
- Building bigger muscles and staying injury-free are not mutually exclusive — programming should achieve both simultaneously.
Exercise Details
The “No Money” Curl
Target Muscles
- Biceps (primary)
- Rotator cuff / external rotators of the shoulder (secondary, stabilizing)
Proper Form Cues
- Begin with arms at your sides, hands rotated outward (externally rotated) — the “no money” position
- Simultaneously curl the weight up while maintaining or increasing external rotation at the shoulder
- At the top of the movement, the shoulder should be in a fully externally rotated position
- Lower the weight back down with control, returning to the starting externally rotated position
- Think: down → externally rotate → curl up as one coordinated movement
Common Mistakes to Avoid
- Performing curls with the arms in a neutral or internally rotated position, which places repeated stress on the shoulder joint
- Neglecting the rotator cuff entirely in a training program while heavily loading the biceps
- Doing standard curls in isolation without considering the shoulder’s involvement
