Have fun with the Infomercial

wow…straight off an infomercial. At least it’s better than shake weight (my next white elephant christmas gift)

PRO TIP: No matter how many 7 second sessions you go through, you will never build a physique like the guy in the video using nothing but this “Workout Bar”.

$19.79 at amazon and 4 stars

Reviews over here say it works fairly well but that actually getting into the higher tension ranges (with leg exercises initially) creates noticeable wear on the spring and eventually weakens the unit.

But you can get three here for the same price as shipping one from there, so it might be worth at least two if you think you’ll be able to stress the thing.

Best price on Ebay is $34.00

Between this and Sellout, I think Woot is trying to tell me something. Fine, I will go for a run tomorrow, Woot. Just get off my case.

If it isn’t the amazing Bullworker!

What sorts of exercises do you DO with one of these? Is it a similar resistance-style exercise tool to resistance bands?

Also, my initial thought was “Can I put it in a doorframe and do pull-ups?”.

Are isometric exercises effective?

Isometric exercise means that you push against something that doesn’t move, such as a wall. Thirty years ago, most weightlifters and athletes is sports requiring strength used isometric training to make themselves stronger. Athletes don’t use isometric training much anymore. The strength gained through performing isometric contractions is only within 20 degrees of the angle you hold. On the other hand, when you lift weights, you become strong through a wide range of motion. Isometrics cause your blood pressure to rise higher than the other methods of strength training. If you have weak blood vessels or heart trouble, you can rupture a blood vessel or develop an irregular heart beat.

According to Dr. John D. Fair, Chairman of the Department of History at Auburn University, the popularity of isometrics was the result of the success of some weightlifters who took synthetic male hormones called anabolic steroids and then claimed that their isometric exercises made them strong. They claimed that they were doing a revolutionary new training method of pushing against bars that didn’t move. The steroids made them stronger by helping them to recover faster from tough workouts so they could do more work. The only stimulus to make a muscle stronger is to exercise that muscle against resistance. You can lift heavy weights, push against special strength machines and push against something that doesn’t move, such as a wall or bar attached to the ground. Isometrics are not used much any more, but the steroids are still used, even though they are banned by most sport authorities.

I was wondering the same thing. My younger brother works out a bit, and recently got a resistance band for his birthday. I saw this come up and was considering doing a bit of early Christmas shopping. However, I don’t want to grab something that is all gimmick and no substance.

Anyone out there have personal experience with this device?

Yes! I’ve been wanting to mention this since this popped up, but the comments section would not work for me till just now!
I actually Had a Bullworker…40 years ago! And it cost me $30 back then!

I bought one of these a year or two ago because I had some credit at my local sporting good store after purchasing stuff for P90X. While it will give you an isometric workout, the number of exercises are pretty limited and it’s really uncomfortable to use. Honestly, I’d save the money and buy some used dumbbells or cheap resistance bands.

This piece of equipment can supplement a home gym, but not replace it (at all).

The amazing thing about this is the wide range of uses!


In for 2. Make a great Christmas gift.

Uncomfortable to use could describe all exercise equipment. :wink: In all seriousness though, would you say that there is a risk of minor injury?

I remember my dad had one of these from before I was born.
