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 %^$#. Obviously,from a stain POV, you are far better off with cloud white. The tiniest imperfection will show on glacier white while cloud white will hide some tiny stain.
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.
A good squat is a deep squat performed correctly. Inadequate ankle and hip mobility often keep lifters from squatting well. How you prepare to squat will determine how deep you can go. Do mobility exercises for the ankles, knees, and hips, then do stability exercises for the core before squatting. Use box squats to perfect your form. Front squats are a good option for those unable to back squat.
