Review: Compact and versatile - Very convenient
Review: Review on item, not the seller. Please read! - At first glance these look amazing and convenient. They're well structured, fairly compact and practically indestructible. For someone looking for JUST weightlifting these are probably your best options and on par with the bowflex's. I've had both for a lengthy period of time so will compare them below if you're on the fence with which one to go with. Sturdiness/reliability. This goes to the powerblocks. They're solid! The bowflex's can feel a little flimsy and have a lot more play in them than the powerblocks. As these are solid iron frames they won't move around and give a good base of support. Function/ ease of use. Bowflex's have this hands down and this is one of the reasons that I wish I'd have kept my bowflex's. The increase of weight for the flex's are (if memory serves) around a kilo or so when you adjust the dial. The powerblocks you can do this also but it means dropping the weight, taking out the bar support, moving the lever to get access to the 1kg weights inside the main housing and then putting all back together to change weight again. It's a right faf!! Bowflex will take 2-3 seconds tops. The powerblocks you're talking about 20 seconds or so. Doesn't sound like a lot and is a little bit picky but when you're having to do this EVERY set it just adds more and more time on there and can hinder your gains when doing drop sets, supersets etc. Not only that but if you want to do circuit style training it just becomes a right pain. You could leave the weights in there but then you're talking about a 4kg gain if you want to move up in weight for the next set. Not so bad for bigger muscle groups like chest/back but for smaller ones like tri's and bi's it can be a case of the weight being too heavy or too light so you're stuck in the middle with what to do! It'd be better if the internal weights came out externally from the bottom or top somehow so it would make changing it quicker. One thing the powerblocks are good for are things like renegade rows / plank walk with db's as they're much more solid than the flex's. Size/feel of the weights. I'd probably give this again to powerblocks but only slightly. They're smaller than the bowflex's and can be stored away better as there isn't a great big base to put them in. The handle sticking out the side of the blocks though can become a little bit of a nuisance as one side you've got the plastic handle that sticks out a bit too much so doing things like bent over rows etc you find you end up pulling your shorts up with each lift, try turning it the other way and you're faced with 2 metal spikes that catch anything and everything when it comes to clothing and if you catch your leg on a deadlift you're gonna end up cutting it for sure. Having said that the bowflex's seem to just be massive in contrast, they're safer in terms of cutting yourself with metal spikes but one thing that made me get rid of mine was the plastic disk moulds that hold the plate in place on the bowflex's. If these become warped/damaged or cracked, the weights will fall out! Not safe if you're doing this bare foot or half way through lie down skull crushers! There is no way to remedy this except getting it stripped down and replacing the parts but you need to know exactly the right position for doing this or the weights won't line up and you will have just wasted the money you spent. To summarize, for small increases in weights, fast style workouts including drop sets, circuits, full body workouts etc then go for the Flex's. For someone just wanting to work one body part at a time, where time isn't an issue and you can go at your own pace. And that prefers a smaller more robust DB then go for the blocks. ☺️

## Questions & Answers

**Q: Are these weights expandable I see two answers?**
A: There is the Powerblock Pro 50 which is what this is and is not EXPANDABLE. In other words the stage 2 nor 3 will fit on it. The Powerblock Pro EXP is expandable but is not available on amazon for some reason. I bought the EXP thinking it was the PRO exp and the attachments DO NOT fit it. It has to be the PRO EXP series if you want to add weight or use attachments.

**Q: Are these expandable to 70 or 90?**
A: According to the powerblock website the Pro 50 is NOT expandable, but the Pro Exp IS expandable to 70 or 90.
I have the Pro 50 and you could not expand to 70 or 90 lbs without changing every single weight plate add-on to be heavier.
The main difference I can see between the Pro 50 and the Pro Exp is the Pro 50 weights increment by 5 lbs each, whereas the Pro Exp increment by 10 lbs. So, both the Pro 50 and Pro Exp have 8 weight plates, but Pro 50 goes to 50 max in 5 lbs increments, but Pro Exp goes to 90 max with 10 lb increments. (This is assuming you leave both adder weights in the handle for every adjustment).

**Q: Are these expanded to 90 lbs each set?**
A: The PowerBlock Pro 50 is one of the non-expandable PowerBlock models.
The expandable models have a EXP in name (EXP stands for expandable).
The Pro 50 does offer every 2.5 lb increment up to 50 lbs.
Thanks.

**Q: Is this one not expandable? If not will you be selling the pro expandable block on Amazon?**
A: This set is the Pro 50 which is not expandable past 50 lbs and is not compatible with any expansion kits.  Generally, you would want to look for sets that have "EXP" in the title if you want an expandable model.  Thank you!

Me llego solo una caja con una sola mancuerna. No llegó el par, la descripción del producto indica que debería de ser un par de mancuernas, no una sola.
