consistancy troubles

I think that home gyms are great if you're highly motivated, live far from a
good gym, and you can afford high quality equipment and you have the
space to do it properly. These are important factors. The motivation thing in
this equation is very important because if you aren't using it you will
definitely hear about that soon enough. Some of the strongest guys I know
work out in their garages and so do some of the most inconsistent.

If you want to be a better thrower/athlete, then you will do the things required to make you one. 

Period.
