Questions about "The Wolf"

Thinking of doing The Wolf after seeing everyone else 'enjoy' it so much. I've been working out with Kettlebells for the last 6 months or so, and am in reasonably good shape. I don't have too much excess fat to loose. I'm already eating a lot more than I used to, and eating pretty well. I've built a bit of muscle but feel like I've plateaued a bit.
The workouts I've been doing are mostly from DanielPT on youtube, I just like the pace and variety.

Also I've only got a pair of 12kg and one 20kg. But I think my 10rm wouldn't be much above 12 anyway.

Will this program build muscle on my arms?
What sort of results is this aimed at? Fat loss, muscle building or stregnth?

Keen to hear peoples thoughts before I jump in.
