Higher levels of anxiety, higher levels of staleness, lack of motivation,
as well as ultimately could lead to depression. This is a symptom of a perfectionism. This is something that I experience when I was an athlete-overtraining, not recovering enough, and paying the price. Physically of course with injuries, but also psychologically. What I recommend is between 1 to 4 days of rest a week. Ideally you want to exercise 5 or 6 times a week; at minimum I would say every other day. So it could be 3 or 4 days a week. At minimum every other day. Ideally you may want a little bit more than that. Each time, about 30 minutes; could go all the way up to an hour. The key here is to listen to your body. If your body is hurting beyond the slight discomfort of exercise which is natural, stop. If your muscle hurts, stop. Or on the side of too little rather than too much. Also one of the ways to listen to your body if you are not as sensitive to it, is putting on a heart rate monitor, which is something not very expensive, very useful, very helpful.
