Bill Clarke said:I somehow doubt that kettlebell swings would work as well for grip strength as either farmers walks or dead hangs. For my goals, kettlebell swings wouldn't work as well as sprints. Although the up side of kettlebell swings is that I can do them inside! Also, I don't think buying kettlebells is worth it because they are set weights, so the only way to progress would be to add more weight or less rest, unless I bought more.
Hm, maybe a little bit. RC PE6 looks like a good grip challenge (I'm on RC PE3), but besides that I don't think there is much grip work for awhile.
Actually kettlebell swings builds a ton of grip strength, they also have a very big transfer to sprints. Though, what are the goals you are trying to accomplish with sprints?
A single kettle bell also lasts longer than you think. Pavel Tsatsouline's kettlebel programs like program minimum in enter the kettlebell or program minimum 2 in simple and sinister really gets you to milk the hell out of each weight
