Here are a few differences between men and women to consider w.r.t.  kettlebells  or  

  • Our handle's  diameter is 1.35"- just a hair smaller than  most cast kettlebells - better for small hands. (although not as small as those "milk jug" 9lb (or even 5 lb) KBs.  Krista discusses some of these points (she still owes us some more pics with the foamdiscs  !).  
  • If you scan the kettlebell forums, you'll see many women asking what weight to start with.  This is a non-issue with Kettlestacks. In fact, women often experience a higher initial percentage strength gain than men, so an adjustable is especially attractive for women (unless cast iron doorstops are in short supply). 
  • Women typically have a larger difference between upper and lower body strength, so a weight that would be challenging for pressing (a 12Kg for example), would be trivial with the swing motion .  Again, an adjustable kettlebell is an obvious solution.
  • Some trainers will go so far to avoid the fact that you will need  different weights as to recommend snatches as the primary motion over the much better for beginner motion of Swings .  There's a world of difference (and benefit) between a light swing and a heavy swing; Weight is all relative- since you're balancing your body against the kettlebell's momentum, you need enough resistance to perform the swing motion correctly.  With the swing motion in particular, the quickchange feature allows for a very easy  and quick change of +- 20 lbs, so the Kettlestack weight used for swings doesn't have to be the one you press, clean or otherwise. 
  • The first 4 standard cast kettlebells weights are 9/13/18/26 lbs- That's a big 40 percent jump per increment; We're not stopping you from following the big jump kettlebell doctrine- just providing an easy,cost effective way to "dial in" smaller weight increments if you want.
  • We now sell foamdiscs that let you make a big,puffy comfortable  Kettlestack with just a few plates.

Those are the major points. Please get back with any other questions.
