Similarities
- Both pushing and pulling use a wide, staggered stance, creating a stable base of support that prevents loss of balance during force application.
- Both require core muscle engagement to maintain a neutral spine, distributing forces evenly along the vertebrae.
Differences
- Pushing directs force away from the body, shifting the centre of gravity forward. If the load releases suddenly, the person risks a forward fall. Pulling brings force toward the body, shifting the centre of gravity backward, so a sudden release risks a backward fall.
- Pushing mainly loads anterior muscles (pectorals, anterior deltoids, triceps), while pulling mainly loads posterior muscles (latissimus dorsi, rhomboids, biceps).
