Original Ideas

1.) A thin suit that goes under your clothes while exercising that when it realizes that your body is getting cold it will help your body conserve heat, and when it feels your body getting too warm it will help cool your body down
2.) Sneakers that have weights you can attach to the bottom and then also remove so when you run or do any exercise you are burning more calories without having to use Velcro ankle weights that fall off
3.) A shoe that has a USB that attaches inside that heel of the shoe that tracks time, steps, and calories burned and then you can take out the USB and track your data on your computer
4.) A baseball/ softball that inside the ball has a radar and when you throw the ball you can check on the side of the ball and it has a digital screen where it will tell you the speed in which you threw it
