You've answered your own question.  If done in moderation and rotated with low-impact cardio along with weight training, you should be O.K.  However, in my younger days, the only cardio I did was high-impact.  This proved to be adversarial.  Although I got in shape, my ankles, knees, hips, and lower back could no longer take the punishment.  My cardio now consists strictly of low-impact exercises, and weight training.

The theory is strong.  It should work that, if an athlete were to train under a progressively increasing gravitational pull, he or she would perform proprtionately better under in a lower-gravity environment.\n\nThe converse is true, as proven by astronauts that return to earth after long stints in micro-gravity.  They have been quoted as saying that a standard wrist watch becomes a bowling ball on after as little as 30 days in orbit.

Okay... Here's my two ideas:\n\n 1. Photographic reflexes... The character can watch a person move and instantly be able to reproduce the movement. Their training time would be short because they would only need to understand how to intergrate the system, and listen to the teachers lessons in tactics and strategy.\n\n 2. The person has the ability to absorb the memory and skills of another through touch.

Bodyweight squats and lunges would work good. If you have a treadmill, try using it at a higher incline.
