The question can be answered by comparing the different types of machines available for indoor cardiovascular exercises. To choose from there are elliptical trainers and treadmills. Generally, both the machines are well-equipped to help their users attain their fitness goals. The treadmill provides a good simulation to jogging outdoors and is preferable for joggers who are used to running outdoors. However it has a much smoother surface than concrete and enables you to run for a longer period of time.,Almost all of the treadmills allow the user to adjust speed and incline enabling you to vary your pace which has a desirable impact on fitness. Treadmills, unlike elliptical trainers make the user constantly lift their feet which helps in toning up the complete body and has a positive impact on the bones. This makes it an immediate choice for younger gym goers and compassionate runners. The elliptical trainer is more suited for senior citizens,Without warming up properly at the start of the workout, no one can reach their desired fitness level. Treadmills are better suited for people on a demanding exercise plan. With the adjustments you can make on speed and incline, treadmills help in getting the body sufficiently warmed up before starting all the other body exercises involving weights.,There are many different ways to achieve fitness and improve your health, i would suggest talking to your local gym or health clinic and ask for a specialized fitness program. Once you start on this you will notice that they will all recommend some type of cardio equipment usually a treadmill or elliptical trainer of some sort. Choose the one that is also the most comfortable for you to use so you will enjoy your fitness training,Whether you choose to buy equipment for your home or use one at the gym it doesn’t matter, what really matters is that you use the equipment regularly meaning 4-5 times a week for around 25-45 minutes each time. Work up slowly and increase the difficulty level when your fitness level increases.
