Ray Mentzer Biography

Ray Mentzer was born on December 18, 1953, in Ephrata, Pennsylvania. He developed an interest in bodybuilding at a young age, inspired by his older brother, Mike Mentzer.

After finishing high school, Mentzer chose to focus on bodybuilding. He moved to California, worked as a personal trainer, and continued competing as an amateur bodybuilder.

After years of competing as an amateur, Ray Mentzer decided to pursue bodybuilding as a full-time career. Ray competed in several bodybuilding contests, including the Mr. America and Mr. Universe competitions.

His most notable achievement was winning the 1979 IFBB Mr. America title in the tall class. He also placed well in other competitions, such as the 1980 Mr. Universe, where he finished in the top five.

Life After Competition

In 1982, after several years of competing, Mike Mentzer retired from professional bodybuilding to pursue other interests. Around the same time, his brother Ray also shifted his focus away from the competitive stage.

Building His Biggest Physique

Although he was no longer competing, Ray continued training intensely. By 1983, he followed various workout routines, including the well-known Heavy-Duty Training method. This high-intensity approach, combined with a high-calorie diet, allowed Ray to significantly increase his body weight.

His weight quickly climbed past 250 pounds. While he wasn’t in stage-ready condition, his massive, muscular frame remained impressive. Later, he reportedly reached a peak weight of 275 pounds, a feat that was considered extraordinary at the time.

His arms, measuring over 20 inches and highly vascular, became a defining feature of his physique. Ray also focused on strength. In one of his training sessions, he was seen squatting 900 pounds for two reps.

Later Life and Health Challenges

After retiring from competitive bodybuilding in the early 1980s, Ray continued to promote HIT principles and remained active in the fitness community. However, his health began to decline in the late 1990s when he was diagnosed with Berger's Disease, a condition that affects kidney function.

This diagnosis led to serious complications and ultimately required him to undergo a kidney transplant. Tragically, Ray Mentzer passed away on June 12, 2001, at the age of 47 due to kidney failure related to his illness. Ray passed away just two days after finding his brother Mike Mentzer’s body in the same apartment, due to heart failure.

Ray Mentzer’s Training Routine

Ray Mentzer followed a high-intensity, low-volume training approach called Heavy Duty Training. This method focused on lifting very heavy weights with fewer sets and reps but with maximum effort.

Key principles of his training included:

Low Volume, High Intensity – He performed fewer sets but pushed each set to failure.
Heavy Weights – His workouts included extremely heavy lifts to maximize muscle growth.
Long Rest Periods – He took several days off between workouts to allow full recovery.

Slow and Controlled Reps – Each rep was done slowly to keep muscles under tension longer.
Progressive Overload – Always tried to increase weight or reps over time to build strength.
Time Under Tension – Ray increased training intensity by doing stutter reps and slow negatives.

Example Workout Split

Ray’s training routine typically involved one or two exercises per muscle group. Ray’s workouts varied, but here’s an example of how he might have structured a week:

Day 1: Chest, Back, and Shoulders

Bench Press – 1-2 sets, 6-8 reps

Ray Mentzer believed that a balanced diet was crucial for building muscle and maintaining overall health. Ray consumed a balanced diet with foods from all the major food groups.

Ray Mentzer followed a high-calorie, high-protein diet to support muscle growth and recovery. Since he trained with high intensity, he needed plenty of nutrients to build strength and maintain his size.

Carbohydrates made up a significant portion of his daily calories—over 60%. He believed carbs were essential for energy and muscle growth.

I got the shred and gold sculpt pack.

“Love it”

-Garfield

The perfect companion for a summer cutting cycle

“Loved the effects from this Androvar cycle. My strength shot up. I was able to lift heavier and longer. Didn't notice any soreness but I increased my amino and joint support intake as suggested by the reps. By the end of the cycle, my shoulders/arms/chest/stomach were much more defined and my muscles looked a lot harder or fuller. Definitely would recommend this to anyone who is looking to improve their lifts or help get that "mens physique" type of look.”

-Wesley T.

“First time having a PH like Andover, I’ll be 50 in January, 5’5 and 199 Lbs been working out for 20 yrs on and off with a recent lag of about 4 yrs, had to loose about 30 lbs that I gained. Already lost 10lbs and sort of reached a plateau. Started Alpha lean 7 when on PCT,

I don’t take any preworkout either yet I’m able to work Out for 1.5 hours in the gym.”
