Rated 5 out of 5 by from Strength During Coronavirus! Purchased the 32 kg Bells at a very lucky moment before they went out of stock.Funny enough, the day of shipment ,the fed ex guy was unable to pick the box up out from the far end of the truck.I jumped back there opened the box in front of him and he nearly melted with the beauty of this.I said to him."If you want to be able to pick up heavy packages in your truck you need to get these suckers from Onnit".I jumped out immediately and began doing some swings.I couldn't help but work out right then and there, my manly primal instincts took over this ancient relic. Long story short; few weeks later I look like a greek statue with the power of Hercules.Call it whatever you want but I truly think Onnit possessed these kettle bells from the Gods. Thank you Onnit!
