Default The "Bradstock" Jump Squat: Is it a safe and effective exercise?

I have been a personal trainer for over 20 years, have trained numerous Olympic Gold Medalists, World Champions and World Record Holders. I am a two time Olympian and two time World Record holder ( in the javelin throw ). I was born with spina bifida, am now 46 and am still competing. I have never had any back or knee surgery. This is the only lower body weight exercise I do.

YouTube video link:

The "Bradstock" Jump Squat:
http://www.youtube.com/watch?v =CPUN1C7V3B0

I have never told any of my clients to do this exercise or shown any of my athletes what I do - until now. I have found it is an amazinlgly effective exercise for building explosive power without bulking or tightening up?

I believe this exercise would be great for golfers, pitcher, batters - indeed anything that requires a maximum effort.

What is your verdict?

Ouch, My knees hurt just watching that. Then again my knees have not been in great shape for quite sometime. I also don't have the bacground in exercise that you do so I can't speak to how it would work for others.

Excuse so I have to go soak my knees now.

You certainly need some marketing help. After the exciting build up I'd have gladly paid $199.99 for the secret..........as long as your threw in some fat blasting special reports as a one time bonus.

My spine just ripped itself free from my body, tore right through my flesh, and ran away like the creature from alien leaving behind it a bloody trail, yelping like a puppy, after watching that video!

Not so sure my spine could handle the deceleration phase of that exercise, especially with that much weight.

BTW, welcome to the forums. Glad to have you here.

Can you tell us who some of your clients are? It's not every day we get trainers who've trained olympic athletes in here.

really bad for the knees and I see wear and tear on that guys knees. To me, it does not look like a safe and effective exercise at all and defiantly not for golfers, pitchers, batters, etc. This will ruin athletes knees using this much weight.

By the way, pitchers, batters, and golfers do not jump with weight by the way. They need plyometric work and explosive/reactive work.

Are you really a personal trainer by the way or are you just spamming us or messing with us? Tell the truth please.

No this is not spam.

Yes I am a certified personal trainer.

I am sorry you think I am an "idiot"...maybe not the sharpest pencil in the pack, but an idiot?

I assumed that you were serious since you didn't seem to sell anything and not an idiot because I give everyone the benefit of the doubt but I do have a question. What is the potential benefit that you can get from that lift that you could not get from a less dangerous lift that would justify the obvious risk of injury?

Kelly Baggett uses similar Jump Squats.
Benefits and Application of Jump Squats

Quote:
1/4 jump squat with reset- This variation is just like the rhythmic jump squat except you reset yourself prior to each repetition. This will enable you to fully concentrate on each repetition. So, on these, just like the rhythmic jump squat, the focus is on the takeoff and getting as high as possible. The performance will be just like the vertical jump the only difference is you will have load on your back. I prefer to use this variation most of the time. The loading will range anywhere from 15-60% again depending on the athlete. Heavier variations are used to develop more strength-speed and lighter variations for more speed-strength. The rep range will be anywhere from 3-8 per set with an average of 5 sets per session.

Famous or not that exercise still looks painful and potentially damaging to most parts of your body.

If you watch the video he posted, you will find that it and the other 33 videos he has on youtube are in the same style as the artwork he is displays on the sites I gave links too.

Still not sure how that prevents someone from pretending they're someone famous. That only proves that Roald Bradstock is real, not that this person is in fact Roald Bradstock.

And that's not to say that this gentleman is NOT Roald, but only that your argument is logically invalid.

Jeez people... why the cynisism? Please don't call new visitors to the forum "idiots." I haven't tried these exercises, and I admit that it looks painful, but I'm not going to summarily dismiss someone like that. I didn't see anything for sale, so I would hardly consider this spam either.

Roald, my apologies for some of the reactions. I would like to hear more about these bradstock squats, and some of your other training methods.

Right. But that can be said of any famous writer that has come here when they first post. The truth would come out soon enough without us needlessly insulting new people.

Welcome to the boards Roald.

I'm a big fan of jump squats but that seems like a pretty high load. About what % of your max is that weight? Doesn't that put a lot of extra pressure on the spine? Have you had many athletes get back injuries from using such a high load?

I'v never tried jump squats, but if that is all the ROM they require, I wouldn't be afraid to try them.

Well, I don't have the athletic background, but that just looks so potentially dangerous to the spine. I know the spine can take a great deal of compression loading, like > 10x what is can take for shear loading, but still...

I concur. And didn't call anyone an idiot. I simply asked if it was spam, because it seemed like an odd post.

I understand why certain coaches use jump squats with relatively light loads for high reps, but don't know why anyone would do a high load/low rep version.

How would that possibly help a golfer, and what are the odds said golfer will end up injured?
I'll put some money on them getting injured.

No self-respecting strength coach would work with a golfer anyway. *runs from tomatoes*

To Clarify:

The video of me doing the jumps squats was at the end of 9 months of training and 5 periodization cycles. Also, i have been doing this exercise for years.
There is a direct correlation, at least for me, with increasing the weight and my throwing distance.
FYI: I never said I use this exercise in any of my athlete or clients - just myself - at least right now.
But if I was to use it I would use much lighter weight for saftely, liability and just plain common sense.
I asked a question: Is this safe and effective.
"All you have to do is leave the ground - right" That is the question I asked in the video. Ignore the weight I am using for a second - do you think the exercise is effective or would be effective on others?
Thanks for all your comments thus far

Given that Kelly Bagget uses them, and it's hard to argue with his success in training vertical jump, they certainly work. He never uses more than 60% of system weight. I've seen 40% quoted by other coaches that 40% should be tops, another says 30-60 is best. So unless your squat is 800, you may be using too much. Of course results matter. If you used less weight, you would get more altitude in your jump. I assume that you use maximum force with every jump, it wouldn't make sense otherwise. That means the landing force would be no different with a lighter weight than you would experience at the weight you are using.

In my opinion, doing them with heavy weight would be no worse than with lower weight and you obviously know what works for you. Few people could harness the power that you can to get off the ground with 400#.

Given that squat jumps are essential training for your any sport requiring lower body power, the question becomes, what are the optimum parameters for power production as applicable to your sport. I don't know the answer.
