Benefits of Unstable Load Training with the PKB
What is the Portable Kettlebell?
PKB vs. Iron kettlebell
"The PKB is very well constructed and most importantly to us, very light!"
"Cool product and great idea!"
Greg Amundson, founder of CrossFit Goal Setting and former owner of the world's first CrossFit gym.
"I was able to fit 50lbs of pebble and sand and it feels like an 80lb metal kettlebell! It is a more difficult workout because it's not rigid. I'm buying a few more!"
Hank Segura, NM
"I love to take my PKB Sandbag with me to the beach. People always stop to ask about it - it provides an incredible workout on the go!!!"
Gabrielle Lynas, San Diego
