Today i seen this old dude jogging backwards does anyone else do this?

does it work out different muscles? does it burn more calories? or is it just preference?

this old dude is like a local legend he's like 50 something and runs in all the marathons and always finishes in the top 5 most are firsts.

i'm curious i jog 5km a day and bike for 10km..i work out nearly everyday.. mostly abs and chest.. i kayak every weekend..

i used to weigh as much as 307 pounds now i'm 190 6'1..

one more question does anyone know of ways to get rid of extra skin? without surgery.. trying to get tighter abs.. its annoying not to have a 6 pack..

anything would be of help

There still may be some fat in your midsection, but I hear you about the skin. Besides staying hydrated, adding mass to your chest, back may help to pull some of the skin upwards. You could try creams, but I've heard they don't do much.

zing nice work my friend

no

The old dude had to take a shit and running backward took his mind off of it.
