I would recommend getting pairs because there are so many more options and you can break them up into singles so you can train groups easier.

I agree with you completely that dumbbells can be used for a lot of kb exercises, but the off center of gravity of the kb and the fluidity of movement is something that is hard to replicate.

All of these implements are just tools, the more important key is “how” do you use them.

For someone looking to start up a training facility, do you have any recommendations on kettlebells in terms of what miht be a good idea to purchase and what would be better to save for down the road when you have more money to play around with. I already had a lot of equipment, dumbbells, and free weights from a neighborhood gym, but now that I am looking to move into a facility, I was considering adding in a few extras. Kettlebells seem like a nice complement to all of the other stuff, but I am just wondering about things like whether to go with singles or pairs (since things like swings and get-ups would only require 1 bell at a time but some other movements would still be best with two- bottoms-up presses likely being one of them), what sizes to get (since some would likely receive heavy usage, while others would receive less……namely bells on the very small and large end of the weight scale), and the fact that the kettlebells may be used in more of a conditioning role in a lot of instances (which would not require as large a selection of bells).

The other reason I ask about this is because dumbbells are just as good (or possibly better) than kettlebells for many things, but there are some things where kettlebells provide an advantage not to be had with dumbbells.

Any input would be appreciated, or perhaps a future post on the topic (that is if you think enough other folks would have enough interest to warrant you taking time out to write it).

In any event, thank you for reading my message.
