Will doing weight training and pilates on different days hinder muscle development and weight loss?

Can you answer carpedeim281’s question about Bodybuilding?:

I do weight/strength training 4 times a week with a day of rest in between. I just signed up for pilates and I wanted to know if doing pilates on those days that my muscles are “resting” will hinder or not help my muscle development and weight loss? Or can I do them on the same day? Any advise?
