Karen answered your first question perfectly...I might help with next one
"Exercise and physical activity fall into four basic categories — endurance, strength, balance, and flexibility. Most people tend to focus on one activity or type of exercise and think they're doing enough. Each type is different, though. Doing them all will give you more benefits. Mixing it up also helps to reduce boredom and cut your risk of injury."
For me, I like to do includ weighted workouts, different kinds of cardio(like running, dancing & skating), yoga & some martial art training. Mixing it up will trigger more muscles + stretching them up to avoid muscule cramps & end up with an overall healthy toned strong body.
Hope that answers your question...good luck
