Biking in the city

The hubby went back to his hobby--biking. Some of my friends say he already lost a couple of pounds. But I cannot really tell because we see each other everyday and noticing some like that is very hard to tell. I'm thinking of giving him usplabs jack3d, it's a pre-workout supplement so that he cannot get sick just in case he over do it. He wanted to go out biking in the mountains but I think he's still not ready for it yet. Maybe a month or two biking in the city for now.
