The workout equipment you purchase will be a matter of personal preference and your own budget. You should choose something simple like a set of hand weights, or something more complex like an all in-one system. There is no right or wrong answer to your workout needs. The best equipment for you to buy will be whatever you are most likely to use.
Simple Solutions…
If you are on a tight budget or you have limited space around your own, you should go with smaller, simpler, workout equipment. This could include weights to use while doing aerobics to add resistance, a jump rope, or mini trampoline. These are all relatively inexpensive and can fit in small settings. If you are new to working out, they may also be a good way to ease into using exercise equipment. You can also get more complex or expensive equipment later, once you are sure you’ll stick to your plan. 
Larger Selections…
There are a wide range of cardio exercise machines you have to choose from. The most popular are the treadmill, the elliptical, and the stationary bike. There are also variations available that combine aspects of all of these things. There are pros and cons to any equipment you may consider, so you should think about your purchase decision carefully.
Treadmill: A treadmill is a machine that allows you to walk in place on a moving conveyor belt. Most are electrically powered, but some are moved by gravity moving against the belt as you step. The latter options are usually a lot less expensive than electronic ones. If you are on a budget, consider one of these. Some treadmills also fold up to fit under beds or in closets when not in use.
Elipitcal: This is a type of machinery that combines the walking movement of a treadmill with a back and forth motion with your arms and legs. You typically hold on to two handles and place your feet in small padded holsters. Then, you move them front and back as quickly as you can. Some allow you to add resistance by choosing harder settings. Most of them do not fold up for storage, but they can be found for reasonable prices.
Stationary Bike: A stationary bike is exactly what it sounds like. It’s a bike that you pedal, but it stays in place. Some have handles that you move back and forth for added movement and calorie burn. You can also choose different difficult settings with a stationary bike to increase the resistance or lower it based on your fitness needs.
When choosing between these, and other, options, you should go with whatever looks like fun. Everyone enjoys doing different things, so what works best for one person may not be the best for someone else. The most important thing about exercising, is that you do it!
