Summary
Jeff Cavaliere from AthleanX presents two targeted techniques for developing the upper chest near the collarbone — a pressing tip to maximize upper chest activation, and a compound exercise that combines an incline dumbbell press with a sit-up. The approach emphasizes athletic, multi-muscle movement over static, isolated exercises to build both muscle and functional power.
Key Points
- The upper chest near the collarbone is commonly underdeveloped because most lifters don’t apply targeted technique during pressing movements.
- Thumb rotation is the key pressing tip: at the top of an incline dumbbell press, allow the thumbs to tilt upward toward the ceiling, which increases upper chest activation and creates a stronger squeeze in that region.
- Never descend past 90 degrees at the elbow during pressing movements to protect shoulder health and joint integrity.
- Controlled pacing matters: rushing through reps reduces time under tension, which is critical for muscle development.
- Static exercises produce stagnant results — incorporating movement and multiple muscle groups simultaneously builds more power and a more athletic physique.
- Combining pressing with a sit-up allows the upper chest to be trained alongside the core and shoulders in one dynamic movement.
- Recruiting more muscle groups in a single exercise increases overall muscle activation without taking focus away from the primary target muscle.
Exercise Details
Incline Dumbbell Press with Sit-Up (Compound Variation)
Target Muscles
- Primary: Upper chest (clavicular head of the pectoralis major)
- Secondary: Core/abdominals, shoulders (anterior deltoid)
Proper Form Cues
- Set up on an incline bench with dumbbells in hand
- Lower the dumbbells slowly and under control — never dropping the elbows below 90 degrees
- At the top of the press, allow the thumbs to tilt upward toward the ceiling to enhance upper chest contraction
- After completing the press, perform a sit-up from the incline position to engage the core
- Lower back down slowly before initiating the next rep
Common Mistakes to Avoid
- Pressing too fast without controlling the tempo — this sacrifices time under tension
- Lowering the dumbbells past 90 degrees, which places unnecessary stress on the shoulder joint
- Ignoring the thumb-tilt cue at the top, which is the primary trigger for upper chest engagement
- Treating pressing as a purely static movement with no variation or athletic intent
Sets/Reps

Incline Dumbbell Press (Tip-Only Variation)
Target Muscles
- Upper chest (near the collarbone)
Proper Form Cues
- Sit back on an incline bench with dumbbells
- Lower with control, stopping at 90 degrees of elbow flexion
- Press up and tilt thumbs toward the ceiling at the top of the movement
- Maintain a slow, deliberate pace throughout
Common Mistakes to Avoid
- Rushing the movement without intentional pacing
- Failing to apply the thumb rotation cue, reducing upper chest isolation
