It depends on your body's reaction to it. If like you say you feel fine, then it should be okay. I wouldn't expect to be breaking strength records with that arrangement but if it makes you stronger for your sport, then go with it. I would be mindful that your soft tissues (especially the connective elements like ligaments and tendons) will still be fatigued from your early morning session, and that you risk an elevated risk of injury in your evening session (both acute injury from not being completely rested, and chronic due to interfering with the repair process). You will not be 100% fresh despite feeling it.
