"All my life I have been overweight, when I was in high school I was over 230 lbs, Poor Diet and nutrition, In Nov 2010, I was 27 years old and the largest I had ever been in my life at 336 Lbs, something needed to change, I was told by several doctors that I would develop Diabetes and was in very poor Health. I decided to change my diet and start doing a morning Routine, which was in part based on Power 90 (the basic version of what would become P90X) I lost 30 lbs, but got stuck, Frustrated and bored with the content, I needed something more. I then got a Bowflex Utlimate 2, off Craiglist for a good price ($800) I used this for some time and had some more progress, I was down about 40 lbs but still not having great progress. down about 40 lbs but still not having great progress. Then by chance I saw an ad for USB on a fitness site and decided to look into it, It just seems more interesting and more versatile then traditional weights or workout equipment. I decided to get my Strength Package and I can honestly say it was some of the best money I ever spent on my health, USB bags are built to take any kind of punishment you can dish out, I had tried using a backpack with contractor bags full of sand, they just blew open after a while, the bag is rock solid, and it will make you rock solid!

6 months went by and now a full year after I started I am 246 lbs (lost 90 lbs) working my way toward 100 lbs still. I use the sandbag 3 times a week, I do segments of cardio followed by power lifting the bag with squats and dead lifts. I burn 1200 calories a work out using the sandbag and its one of the only pieces of fitness equipment I recommend to others and use over and over and never get tired of it. It's waiting for me in the gym, like a good friend, wanting to challenge me and bring me to become the best I can!"

Fitness for Life Ultimate Sandbag Training

I’ve probably only heard it a handful of times. People that really don’t mind how they perform in life, just as long as they look good! It kinda reminds me of one of the classic movies from my teenage years, “White Men Can’t Jump!” In the movie Woody Harrelson is so mad at Wesley Snipes… Read more »

Can Ultimate Sandbag Exercises Be Done Wrong?!

At first glance, asking such a question may seem almost “silly”. Any form of activity if it is based on any form of concepts and principles can be done incorrectly right? I mean, you can do a push-up wrong, you can throw a medicine ball incorrectly, you can jog in a manner that sets you… Read more »

Cory Cripe, DVRT Master (Creator of DVRT Movement Strength) It is one thing to say you believe in something, it is another to really put your neck on the line with those beliefs.

The Measurement of True Core Strength

Cory Cripe, DVRT Master (Creator of DVRT Movement Strength) I can’t tell you how many times I’ve heard from people when they perform twisting, turning, rotational, whatever you want to call it exercises – it bothers their low backs!
