If your fat can you really do too much cardio. Not worrying about losing muscle. Just trying to lose fat
For most of my adult life I could not run more than 1 mile without experiencing pain. One day I went into a runners store, one of the specialists had me run in the store barefoot. Turns out that I have extreme flat feet and my ankles roll...thus shin splints when I run.
He then recommended the New Balance 1540 which is probably the ugliest shoes in the world but built for people with foot issues. Since then I have enjoyed running/cardio even more than lifting weights.
Get your feet tested, get the right running shoes and run as often and as long as you can. And to mix it up I started getting cycling. Running is something that you can do anywhere and at any age.
