"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!"

"In Mid-November 2011, I decided I had enough. Didn't have much going for Me, so I decided to Jump right into the Ultimate Sandbag Training Spartacus Workouts! On December 3, of 2011 I started Eating Clean. It was tough getting Started, but I always loved working out, and even more so since I learned about Josh Henkin's DVRT Program. I'm on My 3rd Week of Josh & Troy's Synergy 2.0, Hands down the best program I've ever seen or been on, The Program is simply Genius. Today February 7, 2012 I weigh 219.6 lbs. I haven't broken the 220 lb barrier in over a Year, this is with 3-1/2 Months of Training, that's 30.4 lbs of Weight, I definitely Put on some Muscle, so I know I lost a lot more than 30.4 lbs of Fat."

"The Ultimate Sandbag has added a whole different stimulus to our clients training by engaging new muscles and burning more calories than before.

Getting our clients bodies to change is always done by putting a stimulus on them that they are not used to. The Ultimate Sandbag has made doing that much easier because no one is used to lifting a sand bag.

Using sand bags in your training with your clients, and yourself, is something that you have to experience for yourself before you believe how dramatically useful it is and effective it is especially for boosting the metabolism and what I call creating more "bang for your buck" with any exercise – you get to work a lot of muscles at once. Putting new demands in your training with the Ultimate Sandbag system will lead to better results.

The biggest advantage with the Ultimate Sandbag is the “Bang for your Buck”! You can do more with one exercise by using sandbag training.

I absolutely recommend the Ultimate Sandbag System!"- Rachel Cosgrove, contributor to Women's Health magazine
