Re/pre habilitation
Strengthen weak areas or injuries.
Referred pain is when the painful area is not the actual injury, it is elsewhere meaning if you have pain for example in your shoulder it could be a neck issue.
Shin splints (musculature)
The issue with doing repetitions or extending and flexing at the ankle to strengthen the shin muscles is the level of intensity is to low for many people.
Sitting place left leg over right thigh. Flex shin to bring toes towards shin. Push foot to extended position resisting with shin muscles.
Shoulder impingement
Sitting or standing bring left upper arm parallel to the floor and in line with torso(elbow furthest position from torso). Rotate at the shoulder to move hand above and as far behind elbow as possible (it may no go behind elbow if lacking flexibility). Some level of effort required.
Knees
If able to walk with no issues you can squat down to a comfortable level and walk backwards.
Foot(plantar fascia)
The soles tightening changes the foot shape and can cause injuries such as in the knee.
Place sole on glass bottle and roll it back and forth to release underside of foot.
