Different exercise stances are based on our own motor development:
- Supine - this stance is the starting point, any human can simply lay down on their back, which makes it the least core challenging one during any free weight exercise.
- Sitting - moving from a supine position to sitting can already improve core activation. More involvement from the spine, shoulder and scapula stabilizers is required, while hip and legs are out of the equation. However; when sitting with hips flexed at 90 degrees, lower back muscles are slightly stretched making it more difficult to perform over head movements (ie. seated OH Press).
- Kneeling - similar to sitting, but now hip stabilizers are required to work. This new requirement causes a upwards chain of increased stabilizer activation, which makes this stance more core challenging than sitting.

- Half-Kneeling - my favorite exercise stance; the half-kneeling position requires one knee to be down while the other is up with the front foot flat on the ground (see picture 1.0). This stance challenges your balance because of the linear alignment and little width between ground contact areas. Also, those with tight hip-flexor will be challenge by the hip separation and may develop better hip mobility . The lumbar spine is effectively stabilized by the glutes and trunk stabilizers if you "kneel tall", which allows for thoracic spine mobility development. This is the super-star of stances, making it the go-to position for rotary stability and power development exercises such as cable chops and lifts, and MED Ball throwing variations.
- Split - also challenging on balance; the split stance can vary in difficulty by barely having the knee off the floor, which requires a great amount of leg strength and endurance, or standing tall with one foot in front of the other, in line or at a narrow stance.
- Standing - ...
- Standing on 1 Leg - the hip girdle, and the muscles surrounding it, work very differently when 1 foot is in contact with the floor when compared to both feet down. By centering the body weight on one leg, an increase in hip stabilizer activation occur, as well as gluteus, hamstring, and adductor participation when producing movement. It may be very beneficial for anyone suffering from chronic knee or hip pain, as most cases are caused by lack of stability in these joints.
