Aerobic then resistance or other way 'round?

[Catrin]

What GLC and Oakleaf said I have also found that I just do not do as well with the weights if I do cardio prior to strength training.

I would say, if I had to squeeze them both into one workout, I'd probably mix it up. Start with 15 minutes of cardio to get all warm and loose, then do the weights, followed by the remainder of my cardio workout. Or do circuit training with the cardio mixed in. I'm no expert.

My usual routine is to do my strength training early in the AM. And then do my cardio workout later in the day or that night.

If your resistance training is sport-focused (strengthening the small stabilizer muscles), then do your run or ride first, following the general rule of large muscle groups before small. Less chance of injury due to stabilizer fatigue when you do your sport, and less likelihood that you'll cheat on your strength training when the large muscle groups are already well fatigued.
