Hi Rosalynn
Being sick and dizzy can't feel good. Maybe try just walking and then gradually get into a faster pace or longer walk. It will burn fat. I've been starting to walk and I'm really liking it. I noticed at times where I've started to push myself, I quit and that's not good either. So do what you can that doesn't make you feel yucky cause then you just may want to quit too. Good luck to you in finding what works best for you
