If you only had a few bucks and you needed a kettlebell that could be used for men AND women... You may want to consider the 26lb kettlebell.   

Not that we ever endorse sharing (never works out, ask my siblings) but healthy men and women can both find great exercises with a 26lb kettlebell --- That is if you do not mind the manly pink color!

Who chooses the 26lb kettlebell:

Women who have outgrown their 17lb kettlebell or wants to take their exercises to the next level.
Men who need a good warm-up kettlebell.
Men looking for a lighter kettlebell to perfect their form prior to moving up in weight. 
Men recoving from an injury.
