Slow walk on rock hard roads, and mostly sprint work and good grub , I do a few miles road work a week, but a lot of sprint work. 50yrds,75yrds,100yrds etc etc , walk her round , and then some more , then feed her after 15-20 mins of being in house. Depends what x u got, some just don't bulk out. Try the b+e vetzyme tabs. I find they work.
