Most Full Squat Reps with 300 lbs: 30 by Donnie Thompson (2015 Arnold Classic)

There is no official world record federation for "max reps at 300 lbs full squat" — but the highest verified competition performance is 30 reps by Donnie Thompson at the 2015 Arnold Classic (pro raw division, monitored, depth-judged).

Context

• Thompson: Elite powerlifter (first 3,000 lb total raw w/wraps). 300 lbs = ~60% of his 1RM (~500 lbs).
• Set: Continuous, no racking, IPF-depth (hip crease below knee).
• Time: ~2 minutes.

Other Notable High-Rep Feats

• Tom Platz (bodybuilder): 23 reps × 525 lbs (unofficial, 1992).
• Fred Hatfield (Dr. Squat): 50 reps × 405 lbs (exhibition).
• CrossFit Games: 2015 Event 5: 300 lb squat cleans (not back squats) for reps — different movement.

Why No Official Record

• Powerlifting federations (IPF, USAPL, WRPF) test 1RM, not rep max.
• Strongman has "reps in 60 sec" events — varying weights.
• No standardized "300 lb rep test" across organizations.

Training Value

High-rep squats (20+ @ 60% 1RM) build work capacity, mental fortitude, hypertrophy — but not max strength. Thompson's 30 is an outlier of conditioning + strength.

30 reps @ 300 lbs (raw, judged depth) = the benchmark. Thompson, 2015 Arnold.
