i typically begin my day with a stretch for about 30-40 minutes and another 20 minutes before and after class. try to avoid “watch and follow along” style learning and stick with a 15-20 minute presentation followed by practice. try and use free weights if possible, as they will work more muscles than machines. you need him whether you believe it or not. so, i think you probably have figured out, i really like vinegar and always go for a vinaigrette style dressing when eating a salad.
