Could be many things and could be "treated" with many routines:
- If you have psychological blocks about training, then you could use hypnosis to remove those. Ive used, with sucess, this :
Its a easy self use hypnosis and the one to remove blocks is free. Used many many times.
- If your block is very strong, like someone would hit you so you would do things, ive used, with sucess as well, this:
Not easy to use, takes a long time, but ultra effective. Its like a tour to remove every single possible trauma.
- If you lack energy to do your routines, then i would suggest Chikung routines,
