" Voted #1 Training Studio "



Amazing Results! I’ve never been consistent until I found STAC Fitness a number of years ago. Now it’s 2x per week without miss. The workouts are intense and are varied constantly. I’m more fit now than I’ve been in my whole life. I highly recommend Richard Ruiz and STAC to maximize your workouts. – EKC

It’s difficult to describe a workout with Richard, and what it’s meant to me. I guess because it’s more than a typical workout. Every session is difficult, and I can’t believe what I’m capable of doing. – Heidi K.

A great place to workout. STAC Fitness offers great personal training, and lots of equipment for a studio setting. There’s even an Boxing option for training. Plenty of parking and well located in The Denver Tech center. – Linda B.I find these workouts hard, but very specific. He incorporates exercises that I have never seen from any other trainers. He pushes you your limits but not beyond them. I’ve had different trainers since 1998 and by far Richard Ruiz is the best I’ve ever had. – Steve G.

I consider Richard my passport to great health. I train on average 3x per week. Richard is a pro and he trains for results not show. At age 69, with the help of Richard I have the lifestyle of a 35 year old. – Tom W.
