Hi there,

Lately i have been working out about 4x a week to try and slim down for a confidence boost. i Find myself having a hard time having good effective work out due to several things, such as Knee pain when i do squats, pain in back of knee area when i kneel and stretch legs straight behind me, when i run on tread mill i get very painful back aches, and  i have asthma and i can only run for about 30sec before i start getting dizzy, my ears pop, and i have a shortening of breath. Do i hurt so much because of my terrible calcium intake? I was told by my friend that my back hurts on treadmill because of the shoes i wear, which do not have heel support. I am saving to buy a nice pair of running shoes, but then how do i deal with my breathing problems when i run? I have always had this issue when working out and even dancing. This problem prevents me from really getting the most out of my workout routine. What would you suggest i do or take? calcium supplements? Take a advil before i run? Thank you for your time!
