I am in a real dilemma.

I have some hexagonal weights but I need more weight in order to do the pyramid increase for each BFL set.

Been shopping around but want to maximize my purchase so that I have room to "grow" (as I am able to lift more weight) so to speak. Money is also an issue. I know I have to spend some but I need to keep it minimal. Space is at a premium and I can't afford a huge set or even a weight tree to store everything so I have to think in terms of storage. Also, I am thinking that if I keep buying hexagonal weights, I am more limited in being able to increase weights (i.e. tons of weights lying around and nowhere to put them. Also, outgrowing weights like the 3 lb dumbbells I have already outgrown).

I would appreciate any input as to what you have found works for you as you have gotten stronger.

The gym is out of the question because I can't afford it.
