Where it all started
fitness, injury prevention, + rehab = hystrength

Gregg Hoffman speaking here. 27 years ago, I was enthusiastic about building a fit, shapely body. More specifically, I wanted to be a bodybuilder with the desire to compete onstage.

I was committed to my exercise program for about 3 years, and I did not see much change in my body in spite of the effort I put into it. Then I learned about High Intensity Training through the writings of Dr. Elington Darden.

I learned how to achieve far better results spending much less time in the gym.

Interestingly, the training protocols he recommended worked just as well for women who wanted to have a toned physique, and it was a very effective way for athletes to train to improve their physical conditioning. I just had to tell everyone.

Over time I learned as much as I could about fitness, injury prevention and rehab. Ultimately I created my own exercise program called Hystrength.

Both Sharon and I train and teach other people how to be in the best shape they can be without spending endless hours in the gym.

Co-Owner / Master Trainer / Creator of the Hystrength Training Program

Gregg has a long career in the fitness industry. He has logged over 45,000 hours training people who want to get in shape, has written many books and award-winning articles, received numerous awards and certifications, and has designed and trademarked his own fitness program called HYSTRENGTH.

His desire to become a personal trainer started over 25 years ago when he would enthusiastically prod his friends and co-workers to workout with him.

His passion increased when he learned that there was so much more to exercise…in how little we actually need for our health.

Like many young bodybuilding aspirants, he would devote several hours a week to the gym in the quest for muscle. One day he stumbled on a book called Super High Intensity Bodybuilding written by Dr. Ellington Darden. Dr. Darden espoused a different approach. Instead of committing several hours a week to a routine as per the mainstream way of training, he strongly advocated only three 45 minute workouts a week. The catch was that one would have to put more focus and intensity on every set one would do, but if performed properly, the trainee could see strength gains better than he would see with a higher volume approach. Upon applying the principles Dr. Darden wrote about, Gregg did get much stronger. Thus, his passion for fitness grew.

In his ever expanding quest for knowledge, he studied other fitness disciplines and ultimately designed his own program that he calls HYSTRENGTH(sm).

He has earned certifications from:

  • Sasha and Company
  • American Council on Exercise
  • C.H.E.K. institute
  • Scientific Core Training
  • Scientific Back Training

He has owned and operated two personal training studios called Bodies by Hoffman. He created the HYSTRENGTH(sm) certification program in which he has hired and trainer other trainers. He has also set up an intern program with both Heritage College and Emily Griffith Opportunity school to better prepare those students for the real world.

At present, he is co-owner of Urban Pump LLC, which is a private personal training studio located in downtown Denver.

Gregg has logged over 45,000 hours training people who want to get in shape, has written many articles, and has an ongoing blog about fitness and health.

He is considered an expert author on the subject by E-Zine articles, and has writing awards by Hub pages.

Gregg wrote two books on the topic of health and fitness: Proven Strategies for Cellulite Loss, and Lose the Menopot. Both books are available through Amazon, and he has other book projects in the works.

Among many of Gregg’s achievements, he was voted one of the top 100 trainers in America in the December 2004 edition of Men’s Journal Magazine. His studio, Urban Pump LLC was also voted 14th place out of 85 entrants to the A-list of Colorado.

 Sharon has been a personal trainer for 8 years now. She, along with Gregg Hoffman, is a co-owner of Urban Pump LLC.

Before meeting Gregg, she was the typical aerobic junkie, committing upwards to 20 hours a week working out. She tried them all: bicycling, running, yoga, spinning, and had many memberships to gyms. All of this in the pursuit of having a lean, shapely body.

For all of her effort, she got nowhere. She saw no more tone and shape after several years then when she first started. When she first met Gregg, and asked how often he trained, she was shocked. He only worked out three times a week for no more than 45 minutes each. On top of that, he never did any aerobic exercise. The most convincing thing of all was that he had the kind of toned, defined body that she wanted. She eagerly started the HYSTRENGTH(sm) program under his tutelage, and within six months her body did a dramatic change.

She finally had definition. She was stronger. Much stronger. She had more energy, and most importantly, she had time for a life.

She also noticed other unexpected benefits. She slept better. She handles stress better…and she noticed her skin looking younger! Most surprisingly to her, this all happened when she was 46 years old, when we are supposedly losing muscle and the ability to have a young looking body. “Wow,” she thought. People need to know about this program…everybody needs to know about it! She would “spread the gospel,” to all of her friends and acquaintances, but she never even considered becoming a personal trainer. It was her enthusiasm, though, that prompted Gregg to ask her to go through his certification program.

And Sharon embarked on her 5th career. In her own words “This is a program I so wish I would have known about in my 20’s, certainly after I had my children.” It is a regret…to not have access to this training program when she was younger. You can see her passion in this one statement. It is the driving force behind her love for being a personal trainer. Not only does Sharon train her clients, she does the marketing aspect of Urban Pump LLC. She does it effortlessly, for her mission to get the word out is relentless.

As if all the work she does for Urban Pump is not enough, Sharon also launched her own fitness wear line called Iron and Light Fit. Her clothing line features high quality active wear that transitions into street wear. It is a very stylish line that is versatile as well.

Sharon graduated from Denver University in 1982 with a bachelors degree in graphic arts. This is proving to be an invaluable skill for her job of marketing Urban Pump, LLC. Yes, Sharon had other careers before personal training: Graphic design, Floral design, Real estate agent, and, of course, a stay at home mom.

Sharon has expanded her talents, and along with it, is able to offer new services. She now develops homemade teas that help with healing and boosting the immune system. 

Additionally,  Sharon has mentored under three spiritual healing facilitators to learn how to help people to raise their own spiritual vibration. Doing so helps with removing the negative effects of fear, disease and mental blocks among other benefits.

Our Approach:

Science Based Exercise

There is a science to diet and exercise. A good diet and exercise plan that is well implemented is very effective at creating results, and yet most people fall way short of achieving their goals. There are two main reasons for this.

The first one is simply the lack of knowledge. There is a wealth of information on the internet, in books and other media, and there is no doubt that much of that information is valid. In spite of this, most people still don’t know what to do. There is so much information out there that makes it really confusing for people to figure out exactly what they need to do.

Should I do cardio? What about strength training? Should I throw some tires around? So the exercise enthusiast will dabble. I’ll do a little of this…throw in some of that and we’ll see. This approach leads to sub-par results, and usually a lot of unnecessary time in the gym.

The second reason is motivation. Everybody is unique in how they respond to motivational cues. For most people, going to a gym to workout is drudgery and they do not look forward to it, especially if they believe that they need to do many hours of exercise a week to see changes. We understand that. Gone are the days of the boot camp, in your face type of coaching. It just does not work for long term motivation.

At Urban Pump Personal Training Studio, the atmosphere is non-judgmental and individually motivating so that you can get the most out of your workout, and stay committed to your long term goals. Moreover, the Hystrength training program that we employ takes the guesswork out of your exercise program.

Get in. Get your workout done. Skip the gym. See results in 40 minutes a week.
