WON'T GIVE UP
So i'm I the only one that feels this isn't that easy lol?? I've been trying to pick up the speed of my walking for 2 months now but i can only last a mile or 2 that's why i just start jogging i do this walking and jogging 5-6 times a week/5 miles. I've never been a fast walker just wondering if anybody has similar problems??
