Is it bad to do calisthenics and weights on the same day?

[JamesBob]

Am I hurting my weigh-lifting somehow by also doing calisthenics? I've been lifting weights for a few weeks now and I usually do some calisthenics on the same day. I don't use the same muscle groups as with the weights, but I was wondering if it's a bad idea to burn-up that much energy or something.

Is it counter-productive to the weight lifting somehow?
