If your goal is to have a respiratory and cardiovascular fitness, you can not go wrong with either the tape or the elliptical. A 2004 study published in “The Journal of Sports Medicine and Physical Fitness” comparing the effects of exercise at the same intensity and volume in the tape, elliptical and stair climbing for four, eight and Dooce weeks. At the end of each period, all participants experienced the same improvements in their ability to use oxygen during exercise (a measure of efficiency exercises). The strength of your heart and your ability to work to exhaustion also improved in the same quantities, leading the researchers to conclude that any of these machines can help you get in shape
The deciding factor between the elliptical and tape really up to you and your personal needs. If you just aim for your first 5K or half marathon, you will need to do most of your training on the treadmill; It is more specific to your goal of completing a race. You can still use the elliptical once or twice a week to prepare different areas. Your body could help you choose your team. The ellipticals are low impact, so you have less stress on your hips, knees and ankles. If you experience discomfort in your joints when you run on the treadmill, you can train at the same level on the elliptical without pain.
