The kettlebell handles have an excellent ergonomic grip on their smoothed edge corners allowing for smooth transitions between handholds and between hand offs or double hands grip! The 70 lb./32 KG hollow core Kettlebell made of high quality steel instead of the standard cast iron feels spaceage. Perhaps even other proprietary intellectual properties of metallurgy from distant Planet "Vulcan's" Trellium-D an alloy used in the Delphic Expanse helps! I've preparing for "Pon Farr" coming up in 2030. If I don't fight, they will kill us both! Sometimes "Having is not so pleasing a thing as wanting. It is not logical, but it is often true." I have a blood fever, and the only answer is more Kettlebell!!!! Live Long And Hypertrophic! -Spock ✨ (William)
