Home Shoulder Exercise: Side Delts With No Equipment

Summary

This video demonstrates a bodyweight exercise specifically targeting the side deltoids, requiring no equipment and minimal space. The key concept behind the exercise is relative motion — the idea that a muscle can be trained by moving the body away from a fixed limb, rather than moving the limb away from the body. This approach applies conventional shoulder abduction mechanics to a bodyweight-friendly movement.


Key Points

  • Traditional side delt training relies on dumbbells or barbells (e.g., lateral raises, overhead presses), leaving few bodyweight options beyond push-up variations
  • The relative motion principle is central to this exercise: just as the core can be trained by rotating the top OR bottom of the body, the shoulder can be loaded by moving the body away from a fixed arm
  • The side deltoid is responsible for arm abduction — taking the arm away from the body — and this movement can be replicated in reverse by moving the body away from a stationary arm
  • The exercise is performed in a forearm plank position, meaning the core is simultaneously engaged throughout
  • Difficulty can be increased by lowering the body into a deeper collapse at the bottom, creating a greater stretch on the delt
  • The free hand can either be placed behind the back (hardest variation) or used as a kickstand on the floor for added stability (easier variation)

Exercise Details

Bodyweight Side Delt Raise (Forearm Plank Abduction)

Target Muscles

  • Primary: side deltoid
  • Secondary: Core / stabilizers (due to plank position)

Proper Form Cues

  • Get into a forearm plank, positioned slightly higher up on the elbow than a standard plank
  • Place a towel or pad under the elbow for comfort if needed
  • From the plank, drive the body upward and outward away from the planted arm — the arm stays fixed while the body moves
  • At the bottom of each rep, allow the body to collapse slightly lower than the starting plank position to achieve a full stretch on the working delt
  • Movement pattern: down → out → up

Variations by Difficulty

VariationDifficulty
Free hand used as a kickstand on the floorEasier
Free hand held behind the back (3-point stance)Harder

Common Mistakes to Avoid

  • Not lowering far enough at the bottom — reducing the stretch limits the range of motion and effectiveness
  • Skipping the upward drive — the movement should go out and up, not just sideways

Sets/Reps

  • No specific sets or reps were mentioned; the exercise is demonstrated for feel, with the note that the shoulder “lights up” after just a few reps
