Safe and Effective Weight Training



It sounds too good to be true—a private, once-a-week, 25-minute full-body strength workout. Just you and a trainer in a private, low-key workout studio.

You have probably discovered that we begin to lose muscle mass sometime in our 30s, and it continues as we get older. If we don't replace the muscle, it is naturally replaced with fat. Weight training has been proven to help reverse the process, as well as INCREASE STRENGTH, BONE DENSITY, METABOLISM, CARDIOVASCULAR FUNCTION, GLUCOSE TOLERANCE and BALANCE.

The Workout Garage program is probably not like any you've ever done. Our "slow-motion, high-intensity" weight training is not new; it was developed at the University of Florida School of Medicine in the early eighties. With this workout the major muscles and core are safely worked deeply and thoroughly. So much so that it only needs to be done once a week. The muscles safely reach maximum exertion in a very short amount of time by slowly lifting and lowering (slow-motion) the weight load without pausing between repetitions (high-intensity).

It's perfect for busy adults and an excellent program for seniors. Owner and trainer Jeff Grossman customizes each session to each individual's ability and ensures proper form for a controlled and effective workout.

 Private Workout Studio In Pacific Palisades


No music. No juice bar. No social scene. The Workout Garage is all about a safe and focused, core-strengthening, one-on-one full-body workout. Our slow-motion, high-intensity workouts are done on top-quality weight machines and customized to each individual, and any physical limitations are taken into consideration. (We have clients with hip replacements, knee replacements, arthritis, bursitis, partially torn rotator cuffs and partially torn meniscuses.) Each session consists of single sets of continuous motion reps on each of The Workout Garage's "Big 5" weight machines. Sessions last about 25 minutes and need to be done only once a week. 

The Workout Garage is a comfortable, air-conditioned studio located in a former garage behind a home in the Alphabet Streets of Pacific Palisades. Access is easy from Santa Monica and Malibu. Scheduling is flexible, and sessions are usually available Monday through Saturday from 5:45 a.m. until 5:00 p.m.

Owner and Trainer

Jeff Grossman is certified as a Personal Trainer by the American Council on Exercise. He is also certified to specifically conduct slow-motion, high-intensity weight training sessions. He has been training clients in this unique weight training workout for over 2 years, and he regularly trains over 50 clients a week.

"I have been doing this workout for over 3 years, and I have never been hurt or skipped a session because I didn't feel like doing it. (It's only 25 minutes!) I am in better shape now than I was in my twenties. I'm not ripped and buff, but I am lean and strong. I was 70 when I started, and I have almost tripled my upper and lower body strength. My stomach has never been so firm. My 66-years-young wife, who is not an athlete, started when I did, and she is fit and toned...she looks better than she did when we got married!" — Jeff Grossman
