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
