500 LB Squat with Dr. Joel Seedman on 90 Degree Eccentric Isometrics

Here I’m showing optimal 90 degree squat mechanics with 500 lbs. And yes this is 90 deg joint angles which is significantly above parallel due to tibial inclination.

12 Squat truths.
1.Proper squats under high force high impact scenarios involve roughly 90 deg joint angles at both hip & knee joint.

2.This rule applies to any & all humans regardless of age, height, gender, ethnicity, training background etc.

3.Unlesss you’re competing in the sport of Olympic weightlifting or powerlifter there’s no reason to do loaded squats deeper than 90 deg angles.

4.Maximal ROM and Optimal ROM are 2 very different things.

5.ATG represents max ROM but is rarely if ever optimal ROM under high force conditions except for Olympic weightlifters.

6.Individual differences in anthropometrics & anatomical differences only indicate what’s possible for ROM not what’s optimal.

7.Maximal muscle activation occurs at roughly 90 deg for all the lower body muscles including glutes, quads, & hamstrings.

8.Many studies suggesting otherwise are significantly flawed & do not teach their participants how to squat or given them any level proper coaching or cueing.

9.Sloppy & faulty mechanics such as lack of sitting back & into the hips, flared toes, & lack of full body tension will likely require the individual to reach excessive depth to have any semblance of muscle activation.

10.In contrast when proper cues are implemented & optimal kinematics are employed then max activation occurs at 90.

11.Foundational principles of exercise physiology, biomechanics, & neuromuscular physiology, are congruent with each other indicating 90 is optimal ROM for squats & most movements .

12.The greatest trick the Devil ever played on the fitness industry was convincing everyone they needed to push their mobility boundaries including the need to squat with deeper ROM.

And not a single squat was done that day.

It's knee day boys! Load up more than your muscles can handle, and let your cartilage know who's boss!

[RaineyPowerTraining]

Dudes a "doctor" but doesn't understand degree of angles. Makes sense 😂

[stealthhdx]

Think you should have gone a little lower with that. I have an article you could read if you want it.

[lmc]

baby reps, baby reps, give me baby reps

[anthonycampana]

so this doesn't cause joint pain but using full ROM with a weight that your muscles and tendons can actually handle does? lmao

It's quite far from 90 degree... more like 45

[hugitoburrito]

I literally searched "people making fun of Joel Seedman" because it's so entertaining and this popped up

Backing into the rack with 500, always a wise idea. Thank you Charles Darwin.

I see this all the time at the gym. Dudes loading up the bar with a lot of weight, moving it 3-4 inches, then looking smug like they’re the strongest guy at the gym. Now I know who to blame for this trend.

[Smpn]

bro with that range of motion imma squat 675

[mikejohnson]

Nice quarter squat. Guy looked like his body was about to explode.

[jacobnieves]

If you go to parallel, you're getting stapled

[jakedragon]

If you follow this guy for fitness, stop

[meruemo]

Even by your own standards that's not anywhere near 90 degree. Let alone a below parallel proper squat

[TheMaurader]

I estimate your full to depth squat being like 315, your a novice lifter at best and we don’t take advice from novices

[mrofficial]

If this counts, i have a 800lbs squat!

[carpenterdom]

I think I missed the part where you squat 500lb

[wesleyallen]

You’re exiting and entering the rack backwards

[zrobineu]

You can see this works….. I mean look at those quads!!!
