- concentric contraction
- the muscle shortens to create the movement
- >e.g. bicep curl
- the bicep is contracting - making the movement
- eccentric contraction
- the muscle lengthens to create the movement
- >e.g. the downwards phase of a push-up
- the tricep is lengthening to control the movement
- concentric contraction
- isometric
- the muscles stays the same length
- >e.g wall sit
