Exercise can be broken down into three main types:
Strength exercises: These concentrate on specific muscle groups, creating microtears in the muscle fiber which are rebuilt to be stronger.
Cardiovascular exercises: These work large muscle groups to improve heart and lung health while also burning calories.
Sports: These use strength and cardiovascular ability to perform. Since activity can vary a lot, it's hard to nail down exactly how many calories you're burning or how much muscle you're gaining, but it's a lot more fun than the other types of exercise.
Do you know what piece of exercise equipment you need to get fit?
That's right: nothing! Well, almost nothing. You should have some athletic shoes, and you may want to get some free weights for strength training. Both are relatively inexpensive. There are a lot of good exercise programs out there that only use these two things.
Look at additional equipment less as gotta-haves and more as toys: you don't need a medicine ball, but throwing one around is more fun than pumping iron. The same goes for sports: the better your general fitness level is, the better you'll play.
Your body needs to rest between workouts to repair tissue. Most programs will have three days of activity per week, with a day of rest between each workout. Some people exercise six days a week, dividing their workout routines between two main areas like cardiovascular and strength training or upper and lower body exercises.
The first week you start an exercise program, you are probably going to hurt. Your body isn't used to the new activity, and your form may not be great. If you aren't sure about your form, check out ExRx: they have instructions for every exercise known to man.
