When it comes to building all round size and strength nothing can beat a well equipped gym. No gym can be classed as well equipped without at least one olympic barbell and hundreds of kilos of weight plates. No, the smith machine doesn't count, so your gym doesn't cut the mustard. It sounds like a place for woman and children, not somewhere men are made.

Kettlebells would be better than this gym. In terms of getting stronger, only a small percentage of men will be able to press a 24kg bell overhead. Fractions of a percent of the general population could do a pistol with a 24. Swings will help both your condtioning and build the explosive power in just the right places for a rugby tackle.
