Is there any harm in going to gym 6 days a week and excercise for 30 mins? Mostly, I will be doing 'moderate' weight-lifting. I don't excercise the same muscle two days in a row. I've been excercisging for more than 10 years, although I'm guilty of not doing it regularly, so I want to change things. I refuse to be a bit lazy at going to gym anymore

I read some articles about the importance of 'recovery and rest' after excercise, so I just want to know if you excercise 6 days a week.
