Dynamic Back Stretch
The dynamic back stretch moves your arms and torso through a repeated reaching motion to loosen the lats and upper back, rather than holding one static position. It's a good fit before training, when you want blood flowing and range of motion opening up without spending time in a long, still hold.
Why it works
The lats run from your upper arm down along the sides of your back, and they tend to feel tight after a lot of pulling work, sitting, or simply not reaching overhead much during the day. Moving repeatedly through a reaching pattern, rather than holding one fixed stretch, gradually increases range with each rep and raises blood flow to the area at the same time, which is generally more useful right before training than a long static hold that can temporarily reduce how much force a muscle can produce.
Set up
- Stand with your feet about shoulder-width apart, knees slightly soft.
- Find some open space in front of and above you to reach into.
- Relax your shoulders down away from your ears before starting.
How to do it
- Reach one arm up and slightly across your body, letting your torso lean gently in that direction.
- Feel the stretch travel along your lat, from your upper arm down toward your ribs.
- Return to a neutral standing position with control.
- Repeat on the other side, alternating back and forth in a smooth, continuous rhythm.
- Let your range gradually increase over the first several reps as your back loosens up.
Form cues
- Reach and lean gently, don't yank or force the range.
- Keep the movement slow and controlled, not bouncy.
- Breathe steadily through the whole set.
- Let your range grow naturally rep by rep.
Breathing: Exhale as you reach and lean into the stretch, inhale as you return to standing.
Common mistakes
Bouncing aggressively at the end of the reach to force extra range.
Fix: Keep the motion smooth and controlled; let the range increase gradually across reps instead of forcing it in one go.
Rushing through the reps without feeling the stretch travel along the lat.
Fix: Slow down and pay attention to the sensation along the side of your back on each rep.
Holding your breath while reaching.
Fix: Keep breathing steadily throughout; holding your breath adds tension that works against the stretch.
How to program it
- Eight to 10 controlled reps per side works well as part of a warm-up before an upper-body or pulling session.
- This is gentle mobility work, so it's fine to do daily, especially if your upper back feels tight from sitting or desk work.
- Use it before training to open range of motion, and save longer static back stretches for after your session.
Safety notes
- Keep the reach within a comfortable range; a mild pull is the goal, not sharp discomfort.
- If you feel any sharp pain rather than a stretch, stop and check your range and technique before continuing.

Frequently asked questions
When should I do the dynamic back stretch?
Before training is the best time, since the repeated reaching motion warms up the lats and opens range of motion without the temporary strength dip that a long static hold can cause.
How many reps of the dynamic back stretch should I do?
Eight to 10 controlled reps per side is a good amount for a warm-up.
What's the difference between a dynamic and static back stretch?
A dynamic stretch like this one moves continuously through a range, which suits warming up, while a static stretch holds one position for time, which suits cooling down after training.
Can I do this stretch without any equipment?
Yes, it only needs your bodyweight and enough open space to reach your arms overhead and across your body.
