Power Pack Isometric Exercise Equipment, Portable Strength Training at Home Gym Equipment for Back, Shoulder, Chest, Biceps, Abs, Arm, Ab Workout, Cross Training for Total Body Fitness

I bought a used Bullworker 2 on eBay for about $50. After several months of using it, I was hooked. However, because there is only one level of resistance, it meant that my overhead and behind-the-back compressions could barely budge the thing, yet my leg presses and bent rows would fully compress it.I stuck with it, and didn't want to spend hundreds of dollars on a new Bullworker. I saw the small "Steel Bow' and thought it would be perfect for some of those compressions, as well as the leg adduction. And because these new devices contain 5 levels of spring resistance (easy and quick to change out, btw), it meant that I could now put the Red spring in for my legs (150 lb resistance), and the weaker springs (yellow) for the tough, behind-the back, lower and overhead compressions. So I splurged and instead of just buying a new "classic bow", I bought the entire set, including the Steel Bow and the ISO-Bow and ISO-Bow, and ISO-FLO extension straps. All told, there are 131 different exercise you can do with all this equipment. But I figured, for now, I will only use the Classic Bow mostly, and for some exercises, the Steel Bow. In retrospect, it was more economical to just buy the Classic Bow, because although the Steel Bow seems like it can work more acute angles of the muscle, in reality, because of the variable springs included, the Classic Bow can do the same thing. But so what, they are both very well-made, solid pieces of equipment, and I really appreciate the nice rubber grips so my poor hands don't suffer. All 4 devices (Classic Bow, Steel Bow, ISO-FLO, and ISO-BOW) come with their own booklets. The Steel Bow is essentially a copy of the Classic Bow booklet, with a couple minor exceptions and only one exercise it can do that is not included in the Classic Bow. The booklets are spiral-bound, laminated and very sturdy. Don't worry about sweating on them. I have only two quibbles, one bigger than the other. The big quibble is that the Classic Bow and Steel Bow will SEPARATE if you try and do the reverse-grip and inside-grip compressions, because when you only grab the tubes, it will pull apart from the handle! The only way to prevent this from happening is to unfortunately grab the cables at the same time, which will pull the handles down with the pipes, and it won't separate. The simplicity and ease of changing the springs (a nice feature) also aids in separating the pipes if you only grab the pipes and not the handles or cables for the exercise. You'd think they could put a "lock" feature on it. Oh well, it's not that big of a deal. The other quibble is that I don't think the Bullworker company actually researched exactly what muscles are being recruited for many of their exercises. For example, some of the overhead or behind-the-back compressions, or archer or deadlifts say that certain muscles are worked, but it seems to be off. It's not carefully studied, so you have to either (a) do your own research as you exercise to find out what muscles seem taxed; or (b) just trust in the delightful variation of movements the Bullworker program has dug up. One more final quibble: the original Bullworker 2 I bought was a program built upon isometrics-ONLY. The 65%/7-second study by Hettinger and Muller was cited, and therefore, the wall chart had a complete program of doing only the isometric holds, and NO isotonic (dynamic) movements. This seems to be more consistent with the science and since the Bullworker is a fantastic, safe and versatile device to work out the entire body using isometric contractions (without trying to scrounge for props, such as tugging on doorknobs, hanging off doors, finding heavy boxes and books to lift, etc.) , and a device you can take with you while traveling, there is absolutely no need to introduce isotonics. However, sadly it seems that Bullworker has succumbed to the "dynamic" movement, and recommends the isometric holds "followed by ten reps". Because a single, properly-done isometric contraction is equal to 3 sets of 10 reps (it's true), why include an extra 10 reps, esp. when you have just traumatized the muscle and your CNS is stressed from the isometric contraction? I think it's because of marketing: It just "looks better" to show videos of people moving the device back and forth, back and forth, because that is how we usually view resistance exercise. But it does a disservice to the Bullworker's original pure claims. In any case, you don't HAVE to follow the isotonic (dynamic) part of any routine, but just enjoy all the isometric holds your heart can desire with these amazing devices.

I'll admit it, I spent my hard earned money on the original Bullworker many years ago. At that time, I tried it a few times but, decided it wasn't going to work for me and focused on pumping iron...I wrote it off like I did the Sea Monkey's I bought.Fast forward a several decades. COVID-19 hits, gyms close in March 2020, I do next to nothing until they re-open (limited) in June 2020. My joints ached, nothing felt right lifting, chronic shoulder pain flared up again. Watching the resurgence of COVID-19, I've become concerned that it won't be long before the gym is going to close again. So, I search for a solution.There, on Amazon, is the Bullworker Power Pack. After researching (i.e. company website, YouTube, etc..), I bought it again (old fools...etc..???).Bottom line, I was wrong decades ago and my doubts have vanished. I'm still lifting but, the Bullworker has become an essential part of my strength training. In particular, it has helped me get back in touch with muscle isolation through isometric strength training. With the Bullworker's help, I'm attacking my bad lifting habits and I'm fairly certain, that if necessary, the Power Pack will get me through another gym closure. I haven't even begun to fully utilize it. It's helped me activate muscles I haven't felt a burn in for a long time and that in turn, has helped me to keep the "lift" out of my joints.I apologize for sneering at your product for so long. It is very solid and has a lot of versatility. The documentation is great.Maybe I'll take another look at the Sea Monkey's....lol.

During the quarantine, while trying to come up with ways to continue to work out, I happened to find an old vintage Bullworker in my closet. It had been there for many years and forgotten as my brother was the one who originally purchased it and used it. To my surprise, it was in great working condition. I found some workouts online and went at it... WOW, the machine delivered GREAT results. People I ran into thought I was secretly going to a gym- they were amazed.I decided to purchase the power package (Bow Classic, Steel Bow, Iso-Flo) and it is absolutely the best investment in my body I have ever made. I will not be returning to the gym again. In a few minutes, I can thoroughly and intensely do a whole body workout or I can focus on a certain body part, it's your choice. The results are amazing! A great feature is the ability to change the intensity by simply swapping the springs. This allows people of all training levels to do the workouts, even if they have never trained.Whether you're young or old, male or female I highly recommend making this investment in your body. You WILL NOT regret it. I hardly write reviews but in this case, I felt compelled to do so.

I like the Classic Bow quite a bit, it works out the abs and chest the best, but other muscles will need supplementation. It is very easy to change the resistance levels and it is actually fun to use. The Steel Bow I find to be virtually useless since it has almost zero range of motion, so I don't even use it, if I had known before hand I would have just bought the Classic Bow and not the whole power pack. I usually supplement the Classic Bow workout with a TRX and the Power Twister by Core Prodigy, for a well rounded workout, all three are great for working out at home or while traveling.

Some Background: Back in March 2023, I bought the Bullworker at the full price, $699. I gave it three stars at that time because of the HIGH price - no value at $699 CDN. I LOVED it, but tough to justify the $$$, so I sent it back after two weeks of lamenting. At $449, it's priced exactly where it needs to be! So, I re-bought it on June 29, 2023! The Power Pack are all great products; handy, practical, exceptionally well built, and they give you a substantive burn. A big THANK YOU to the folks at Bullworker for pricing it where the average working stiff (that's me) can justify the purchase. I used my Dads growing up in the 70s. It was great then and better now; tons of product improvements with many resistance options, including the addition of Steel Bow and ISO-FLOW.The ISOFlow and the SteelBow are great, portable units for traveling because they fit in a carry-on. So, if you travel or you want a quick warm-up before you start loading up plates at the gym, feel like skipping the gym and doing an entire workout in your living room, watching TV, a quick pump, or making the Bullworker your whole training program, go for it.  I highly recommend it at $449!!

I have have owned several Bulkworkers over the years and they have always been good although sometimes a little limiting compared to weights. However, this kit is something else it is so compact, complete with carry cases, and well made everything feels sturdily and ergonomically designed. The possibilities with the two bows with spring strength options add to this the ISO-Bow and Extensions and it really is a home gym. Cannot see you would need anything else really. What has surprised me most is how good the simple ISO-Bow is especially for stretches.When my kit arrived I really thought they had sent me a single Bow rather than the entire kit. The is how compact it all is. In each of the Bow bags front pockets are the different resistance strings. The manual for each is in the the bag with the Bow.Also buying this kit together is very good value for money compared to separate purchases so even if you own another Bullworker I would go for this kit.

Attrezzo molto versatile e completo. Racchiude in un piccolo spazio e in un numero esiguo di attrezzi la possibilità di svolgere una valida attività fisica di tipo isometrico. La ginnastica isometrica è particolarmente indicata per incrementare la potenza muscolare, la massa muscolare in maniera naturale. Personalmente uso gli attrezzi del Set per contrastare la evoluzione e la progressione di una sarcopenia, legata alla mia età. Un particolare ringraziamento ad Amazon che mi ha permesso di acquistare un attrezzo che è disponibile solamente negli USA e che per anni non sono riuscito a venirne in possesso, visto le difficoltà operative di acquisto, trasporto e i costi doganali.

Great item. Like I used to prractice 50 years ago.
