Latissimus Dorsi, Serratus Anterior

Upper Body Release: Lats and Serratus Anterior

This technique targets the Latissimus Dorsi (Lats), the large muscles of the back, and the Serratus Anterior, a muscle crucial for shoulder blade stabilization located along the ribs under the armpit.


⚙️ Required Equipment:

  • Foam Roller (shown in the image)
  • OR a Medicine Ball (for a deeper, more pinpointed release)

⚠️ Safety and Setup

  • Position: Lie on your side with the roller or ball placed just below your armpit, resting on your ribs/back.


  • Support: Prop yourself up on your bottom elbow for support, using your feet to control the movement.


  • Arm Position: Extend your top arm straight up, parallel to your body, or overhead, which slightly stretches the target muscles.

👣 Step-by-Step Guide:

1. Locate the Lats (Latissimus Dorsi)

  • Placement: Place the roller/ball under your armpit and roll it slightly backward (toward your back). This puts pressure mainly on the thick Latissimus Dorsi.


  • Settle In: Slowly sink your body weight onto the roller until you find a tight spot.
  • Roll Slowly: Gently roll backward and forward a few inches to confirm you are on the muscle tissue.

2. The "Angel Wing" (Lats Release)

  • Pin: Once you find a tender spot on the Lats, keep the roller perfectly still on that spot.
  • Arm Motion: With your top arm overhead, slowly move your arm down toward your hip and then back overhead (like making a snow angel).
  • Repeat 5–10 times. This "pin and stretch" actively releases the Lats.

3. Targeting the Serratus Anterior

  • Shift: Shift the roller/ball slightly forward (toward your chest) and down along your side rib cage, just under the armpit.
  • Hold: Sustain static pressure on this area, as it is often quite tender.

4. The "Rib Breath" (Serratus Release)

  • Since the Serratus Anterior assists in respiration, we use breathing to release it.
  • Keep the roller/ball still on the tender spot.
  • Take 3–5 very slow, deep, diaphragmatic breaths, attempting to expand your rib cage side-to-side with each inhale.
  • The deep breathing causes the muscle to move and contract against the pressure of the roller.

5. Glide Down

  • Once the high spots are released, gently roll the roller/ball down your side toward your waist by about one inch.
  • Repeat the "Angel Wing" and "Rib Breath" techniques at that new spot.

💡 Quick Tip: Control

  • If you use a medicine ball, it will be much more intense. To lighten the pressure, press harder with your supporting elbow and feet to lift your hips slightly off the roller.
