On each picture you will see 3 symbols corresponding to workout, travel and muscle stress. The symbol that is highlighted is generally what you would use Mooyee to combat. For example, biceps/forearms are usually from exercise pain, not so much general muscle aches or travel.
Each body part graphic will also give you a recommended Mooyee level and sensation. Please note that the S1 does not have all these sensations and will only go up to level 10.
Activation is before movement to stimulate a muscle. You can do this for just 5 minutes to warm a muscle up. If for a medical reason please leave on 15-20 minutes.
Recovery is after exercise, you would put Mooyee on within 2 hours of the exercise and leave it on from 15-30 minutes depending on the size of the muscle and how hard you worked.
Tension is for general discomfort. It is recommended about 20-30 minutes for tension relief but you will feel a difference after 4 minutes.
