I think it could help you, maybe.
You work out, get really tired and worn out. Makes it easier for your body to relax.
If you're relaxed enough, BOOM.
Exercising seems to help me relax when attempting. But it does make it hard to sleep if I do it close to going to bed.
It seems I've read that physical exercise helps rather than hinders. Try working out then waiting until your body is relaxed before you AP.
Very best,
In addition to trying to astral project, I recently started going to a gym. What I'm wondering is if physical training like weight lifting might hinder my attempts to OBE. Would it create added tension in the muscles that would hinder relaxation? Has anyone noticed any problems in this?
