Fred Hatfield – Profile

He Squatted Four Times His Bodyweight in Four Weight Classes

Fred Hatfield – “Dr. Squat”

Fred Hatfield was an elite powerlifter with two World Championship titles and multiple world records. He was also known as “Dr. Squat.” This was partly because he held a doctorate in sports science, psychology, physiology, and motor learning, and worked as a professor at several universities and colleges. Of course, his actual ability in the squat also contributed to the nickname.

He broke numerous world records across several weight classes, and at one point held the heaviest squat ever performed at 460 kg / 1014 lbs. Hatfield enjoyed teaching and sharing knowledge. He wrote over 60 books, many of which became bestsellers and were used as study material. He also founded the International Sports Sciences Association. In addition to that, he consulted Lee Haney in his training on his way to winning Mr. Olympia eight times.

Hatfield was also one of the first Americans allowed to travel to the Soviet Union to study how they trained and to learn their principles and methods.

More than just a squatter

Hatfield was not only great in the squat, he was a strong powerlifter overall.

He started powerlifting in the early 1970s, but already had a background in strength. He had been both a gymnast and an Olympic weightlifter, which was evident in his explosive ability and jumping power.

His first American Championship was in 1977, where he placed third in the 82.5 kg / 181 lbs class. At the North American Championships in 1979, he won with a total of 830 kg / 1830 lbs in the same class, a total that at the time could have been enough to win the World Championships.

World champion without a national title

What makes his two World Championship titles interesting is that he never won a national championship at the senior level. He qualified for Worlds by being the best runner-up in 1983 and 1986. At the World Championships, he was among the American lifters who dropped the least in performance. There are also indications that his academic knowledge may have extended into understanding performance enhancement, but that remains speculation. He won his first World Championship in Gothenburg in 1983 in the -100 kg / 220 lbs class. His second came in 1986 in the Netherlands, in the -110 kg / 242 lbs class.

What makes his two World Championship titles interesting is that he never won a national championship at the senior level. He qualified for Worlds by being the best runner-up in 1983 and 1986. At the World Championships, he was among the American lifters who dropped the least in performance. There are also indications that his academic knowledge may have extended into understanding performance enhancement, but that remains speculation. He won his first World Championship in Gothenburg in 1983 in the -100 kg / 220 lbs class. His second came in 1986 in the Netherlands, in the -110 kg / 242 lbs class.

His best placements at the American Championships were multiple second and third places, which is what qualified him for Worlds. At the 1983 Worlds, he and Joe Ladner (who had won the American Championships) totaled the same, but Hatfield was 0.4 kg / 1 lbs lighter and therefore won.

The federation split and the 1986 Worlds

When Hatfield won his second World Championship in 1986, there had been a federation split.

APF (American Powerlifting Federation), affiliated with WPC internationally, held its first national championship the week before USPF (United States Powerlifting Federation). Many lifters moved to APF, which made the USPF classes less competitive.

In the -110 kg / 242 lbs class, there were two world champions: Fred Hatfield and Dave Jacoby. Jacoby won the national championship, but bombed out in the bench press at Worlds. Hatfield went on to win his second World Championship, closely followed by Swedish-Finn Samuli Kivi in second place.

Other titles

Even though Hatfield never won an open national title, it is worth mentioning that he won Junior Nationals in 1982. At that time, Junior Nationals in the US was not strictly age-based. Hatfield was 39 years old when he won. It functioned more like a secondary national championship with lower qualification standards.

He also won a masters title. At 45 years old, he totaled 855 kg / 1885 in the -90 kg / 198 lbs class and won the American Masters Championships.

Bench press and deadlift

His bench press and deadlift were solid and competitive:

  • Bench press: 237.5 kg / 523 lbs (raw) in the 110 kg / 243 lbs class
  • Deadlift: 345 kg / 761 lbs in the 100 kg / 220 lbs class
  • Deadlift: 347.5 kg / 766 lbs at 111.5 kg / 246 lbs bodyweight

Despite this, it was the squat where he truly stood out.

His deadlift was likely better than what he showed in competition, but after his heavy squats he was so drained that he could not hold onto heavy weights. According to his own accounts, he pulled 825 lbs / 375 kg in training, which is believable, as he often missed deadlifts due to grip.

Four times bodyweight

He is one of the few lifters to squat four times his bodyweight across four weight classes:

  • 327.5 kg / 722 lbs @ 81.5 kg / 180 lbs
  • 375 kg / 827 lbs @ 90 kg / 198 lbs
  • 400 kg / 882 lbs @ 100 kg / 220 lbs
  • 460 kg / 1014 lbs @ 115 kg / 254 lbs*

I have not found confirmation of this in the -110 kg / 242, lbs class, but it is not unlikely. The most I have found there is a 410 kg / 903 lbs squat.

When he squatted 460 kg / 1014 lbs it was the heaviest squat ever regardless of weight class. The year before, he squatted 457.5 kg / 1008 lbs, which was also the heaviest at the time.

He is also said to have squatted 500 kg / 1102 lbs in training by having training partners move the racks forward so he did not have to walk the weight out. This was before the monolift was introduced in the 1980s.

*Fred’s actual weight when he squatted 460 kg / 1014 lbs is not documented. However, he has said in an interview that it was four times his body weight, which would mean he weighed around 115 kg / 254 lbs. This is not hard to believe due to the fact that he performed squats of around 453 kg / 999 lbs at a body weight of approximately 111–117 kg / 245–258 lbs.

It is worth remembering that this was done with equipment, but not like what we have today. By watching old footage, you can clearly see how much more freely they could move in their suits and knee wraps. If you want to learn more about the equipment of that time, you can read about it here.

Training and method

Hatfield developed the training method C.A.T – Compensatory Acceleration Training.

According to Hatfield, C.A.T is one of the most effective methods for developing force. You train explosive strength together with maximal strength. What you compensate for are your weakest positions, where you are most vulnerable. In powerlifting, this is typically the bottom of the lift.

Even if you miss a lift halfway up, the outcome is usually decided in the start. The higher up in the lift you go, the better leverage you get. If we only trained and competed in the top half of lifts, we would lift more weight.

The goal is therefore to apply maximum force from the bottom, on all weights, not just the heaviest. Think about that next time you train above 50% of your 1RM. Apply full force and you might be surprised how light it feels.

Hatfield suggested using C.A.T in the middle phase of a training cycle. First, you build a base with lighter weights and higher reps. Then heavier training, followed by a C.A.T phase, and then moving on again.

C.A.T typically involved weights up to 80%, with sets of 6–8 and 1–3 reps per set.

This type of training later became very common and is still widely used today, sometimes under different names. It has also been popularized by Westside Barbell through their speed and dynamic effort training.

Andy Bolton, the first man to deadlift 1000 lbs (454 kg), also made explosive deadlifts with moderate weights popular. Even Josh Bryant was heavily influenced by this in his training, as well as in the coaching of the athletes he coached. You can see top world-class benchers like Julius Maddox and Jeremy Hoornstra doing speed work.

Age Is Just a Number

Fred’s greatest achievements in the world of strength were accomplished after he had passed the age of 40. This despite the fact that he had already dedicated many years of his life to strength training.

Some might see him as a late bloomer, but considering all the methods, variations, and ideas he applied to his training, that seems unlikely. Rather, it is more probable that his understanding of training and his ability to apply different approaches were key reasons behind it.

Fred performed his heaviest lifts after the age of 40, including a 460 kg / 1014 lbs squat, a 237.5 kg / 524 lbs bench press, and a 347.5 kg / 766 lbs deadlift.

He also claimed to have achieved, again after the age of 40, a 500 kg / 1102 lbs squat, a 375 kg / 827 lbs deadlift, and a bench press variation of 272 kg / 600 lbs.

The Evolution of Weightlifting Weight Classes

Weightlifting is the oldest scandalized strength sport. However, it has not always looked like it does today. At the first Olympic Games in 1896, weightlifting was 1 of 9 sports. These 9 sports had a total of 43 events. Of these, 2 events belonged to weightlifting. The other sports that participated in the Olympics were.

Wrestling
Tennis
Swimming
Athletics
Shooting
Gymnastics
Fencing
Cycling

Despite the fact that these sports are still part of the Olympics today, both the sports and the events look different. The same applies to weightlifting. Weightlifting consisted of two events then as now, but they were not the same events. One-hand lift and Two-hand lift, which involved moving as much weight as possible from the ground to straight arms overhead. At that time, there was no total; competitions were decided event by event.

The competition movements in weightlifting varied between one-hand and two-hand lifts during the late 1800s and early 1900s. It was not until 1928 that the competition model was established, setting the standard with Press, Snatch, and Clean & Jerk. Later, from 1973 onwards, the press was removed, and only Snatch and Clean & Jerk remained in the sport.

Regarding weight classes over these 130 years, they have looked different. Weight classes were first introduced in 1913. Before that, no consideration was given to bodyweight. Since 1913, weight classes have changed several times. Initially, classes were only added. The super heavyweight class up to and including 1968 started from +90 kg / 198 lbs. It was not until 1969 that the +110 kg / 242 lbs class was introduced, and with it the -110 kg / 242 lbs class.

Later, in 1993, the first wave of weight class changes occurred. If we consider that in 1913 a framework for weight classes was established and only expanded from there, and that the first major shift occurred in 1993, then a total of 5 weight class changes have taken place, including what is seen in 2026.

The reasons behind these changes are primarily to erase old records and create conditions for new records to be set. Of these weight classes, several have returned, but not with their old records. Some of these classes and their records, and when they were set, are as follows:

-60 kg / 132 lbs class (1913–1972)
Snatch: 152.5 kg / 336 lbs – Naim Süleymanoğlu 1988
Clean & Jerk: 190 kg / 419 lbs – Naim Süleymanoğlu 1988

-75 kg / 165 lbs class (1913–1972)
Snatch: 170 kg / 375 lbs – Angel Genchev 1987
Clean & Jerk: 215.5 kg / 475 lbs – Aleksandar Varbanov 1987

-110 kg / 242 lbs class (1969–1992)
Snatch: 210 kg / 463 lbs – Yury Zakharevich 1988
Clean & Jerk: 250.5 kg / 552 lbs – Yury Zakharevich 1988

+110 kg / 242 lbs class (1969–1992)
Snatch: 216 kg / 476 lbs – Antonio Krastev 1987
Clean & Jerk: 266 kg / 586 lbs – Leonid Taranenko 1988

Yury Zakharevich

New records or standards must be achieved within the same classes in order to be recognized as records.

-60 kg / 132 lbs class (2025–)
Snatch: 141 kg / 311 lbs – Standard
Clean & Jerk: 173 kg / 381 lbs – Theerapong Silachai 2025

-75 kg / 165 lbs class (Introduced 2026)
Snatch:
Clean & Jerk:

-110 kg / 242 lbs class (2025–)
Snatch: 196 kg / 432 lbs – Akbar Djuraev 2025
Clean & Jerk: 237 kg / 522 lbs – Standard

+110 kg / 242 lbs class (2025–)
Snatch: 218 kg / 481 lbs – Standard
Clean & Jerk: 260 kg / 573 lbs – Standard

All lifts in all classes were higher in the past. The only result that is higher in the new classes is the clean & jerk, where a standard of 218 kg / 481 lbs has been set. The heaviest snatch in the +110 kg / 242 lbs class up to 1992 was 216 kg / 476 lbs. Much of this is claimed to be linked to more widespread doping in the past, and that it was easier to both use and avoid detection.

The heaviest snatch and clean & jerk ever performed were by Lasha Talakhadze. At his best, he lifted 225 kg / 496 lbs in the snatch and 267 kg / 589 lbs in the clean & jerk. However, Lasha was caught for doping in 2013 as a teenager, before achieving these results. He also weighed in at 177.45 kg / 391 lbs when he made these lifts.
