Dear, Blake Fit

Treadmills are good for your bones and muscles. Exercise helps your bones and Treadmills are exercise. Treadmills are most popular because when you run on them you can go as fast as you want. Next is Stepmills you can run or walk on them they are kind of like Treadmills but it doesn't go fast by itself you have to run fast. Jacobs ladder is good for your muscles to. Jacobs ladder is a ladder that you do exercise on. Ellipticals are good for running or walking. They are good too and are kind of like treadmills.

Sincerly, Mateo

Dear, Blake Fit

The best cardiovascular would be treadmills because they are good for running and it helps with your health. They also help your bones and you can run fast or walk. They cost a lot but they are better than the other ones. The second one would be stepmil because they don't cost that much and they are good. They are similar to treadmills but they cost less and they are good for health. The third would be elliptical because they don't cost that much and are similar to treadmills and stepmils. You can also run or walk on them like the other machines.Ellipticals look different but they are like treadmills. You shoudn't get jacobs ladder because it costs to much and it is not that good. I rank treadmill first stepmil second elliptical third nd jacobs ladder fourth.
