Back & Core — Dynamic Stretches
The back and core dynamic stretches prepare the spine for the rotational, flexion, and extension demands of training. Where the neck and shoulder warm up addresses the upper extremities, back and core dynamic work prepares the structural center of the body — the region that stabilizes and transfers force through every movement in the session ahead.
The thoracic spine in particular benefits significantly from dynamic preparation. It’s a region designed for rotation that modern daily life rarely challenges through its full range, which means it tends to arrive at training sessions stiff and underactivated. Cat cow, thoracic rotations, and the inchworm progressively restore that mobility and prepare the spine to move well under load.
The inchworm deserves particular mention as one of the more complete warm up movements available. It moves through a hip hinge, a plank position, and a spinal extension in a single flowing sequence — warming the hamstrings, activating the core, and preparing the shoulders simultaneously. If time is limited and only one back and core dynamic movement is going to happen, the inchworm covers the most ground.
Reference Card
Region: Back and core Type: Dynamic — moving through range of motion Best Used: Before training as part of a warm up Repetitions: 10–15 per movement
Movements
- Cat cow
- Thoracic rotations
- Standing trunk rotations
- Inchworm
Considerations
- The thoracic spine responds particularly well to dynamic rotation work before training — stiffness here affects movement quality across the entire session
- The inchworm is one of the most complete warm up movements available — prioritize it when time is limited
- Cat cow is appropriate before any session — it moves the spine through flexion and extension gently and effectively
- These movements prepare the core for the bracing demands of compound movements — don’t skip them before heavy lower body or upper body sessions
Programming Notes
- 3–5 minutes covering all four movements is sufficient as a warm up for this region
- Works well as the middle stage of a full body dynamic warm up after neck and shoulder movements
- Particularly important before heavy compound sessions involving squats, deadlifts, rows, and overhead pressing
