When purchasing home exercise equipment you should know your goals of what you want accomplished. You should know what changes you want in yourself and what you want to workout. You should also know the safety of the equipment and if it is safe for you to use it. I hope this helps!
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.
Though each type is described separately, some activities fit into more than one category. For example, many endurance activities also build strength. Strength exercises also help improve balance.
Endurance- dancing
Strength- Lift weights
Balance-standing on one foot
Flexibility-yoga
