Corian will stain and scratch easier than quartz but can be refinished. Chances are nothing will happen to the quartz but if it does the you are %^$#.

Squats are a functional physical activity, offering you spectacular benefits. If squats are performed consistently and with perfect form, they are one of the most powerful movements you can possibly do to tone your body.
How low you go when you squat determines which muscles you'll target. Deep squats, in which your hips descend below your knees, focus on the glutes. Squatting to 90 degrees targets the quadriceps more. Because the hamstrings play a stabilizing role, squat depth doesn't affect them.
