When I started sandbag training, I was coming from an endurance sports background. I was a swimmer through high school that led to triathlons and eventually placing as an amateur. I was lean and light with a limited capacity for moving heavy weight.
I found sandbag training very useful but still preferred the size and versatility of my iron kettlebell. The only problem: I traveled for work and could not pack the “bell” with me.
Out of necessity, I merged the two weight training concepts into one and developed the Portable Kettlebell, or what I referred to at the time as "the kettlebell sandbag."
It could hold up to 40 pounds of sand then easily be emptied and packed for travel. I could store it on the floorboard of my car and not worry about it sliding around and becoming a projectile during traffic stops!
With the Portable Kettlebell, I learned and eventually could practice cleans, presses, squats, snatches, windmills and deadlifts ANYWHERE, ANYTIME.
I could do more than body-weight exercises while easily add or subtract weight. Of course it helps if you have sand or other similar fillers readily available, like pea gravel, dirt, rocks, etc. But if at home or in a hotel room, you can use the TANK Water Bladder and train with water!
The PKB was also softer on my forearm and floors and provided the benefits of unstable load training!
In other words, not only does the sand inside the PKB shift slightly but so does the bag itself due to the webbing-handle construction. Unstable load training makes certain muscles (stabilizers) work harder and more efficiently to stabilize the weight – giving you more bang for your buck with less weight when compared to iron.
That´s right, it´s harder to train with 30 pounds of sand than with 30 pounds of iron!
I truly hope you enjoy implementing the Portable Kettle into your routine and look forward to receiving your updates and notes from the road - or the gym!
