Will glute/leg focused cardo (specifically hills/inclines) along with my regular weight training while dieting (AD style) allow me to continue to shape and keep the muscles, or can it lead to overtraining and thinning those muscles?
REAL overtraining is extremely rare (I’ve only seen it twice in my career, and I worked with over 2000 athletes) and most of the time it is a neural or hormonal/adrenal phenomenon rather than a muscular one.
Muscle tissue actually recovers very fast from a training session, it’s the nervous system that can take a while to get back up to par after a few grueling sessions.
Adrenal burnout is also a possibility if the amount of overall training is excessive compared to one’s recovery capacity and if this situation is maintained over the long run.
Cardio exercises focuses on the glute area is normally very low in intensity (when it comes to CNS involvement) so the risk of CNS fatigue is fairly low. Obviously it increases as you switch to more intense form of energy systems work, like sprints for example. But moderate intensity cardio should not negatively impact the CNS.
Excessive low intensity cardio can, however, have a negative impact on your hormones. Specifically it can lead to elevated cortisol levels which might lead to muscle loss over the long run.
Excessive cardio can also lead to adrenal fatigue by forcing your body to overproduce catecholamines and other ‘fight or flight’ hormones.
So yes, excessive cardio can eventually lead to muscle loss. But the amount necessary for that to happen is very important, and anybody who can listen to their body will see it comming from ten miles away!
Now, the muscle loss will not necessarily be muscle-specific. In other words, just because you are doing glutes-focused cardio does not mean that you will lead your glutes first.
Cardio doesn’t cause a ton of muscle damage due to the lack of loading and the very small amount of eccentric work (when you switch to running, the eccentric stress increases drastically though). So I wouldn’t worry too much about it.

Thanks Coach!
That is excellent news because I like doing incline work for cardio and need to bump up the amount of cardio that I am currently doing. Still, I am not going to be doing excessive amounts of cardio, so I am good to go on that! (:
