Question 1

Are these weights expandable I see two answers?

Accepted Answer

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.

Question 2

Are these expandable to 70 or 90?

Accepted Answer

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).

Question 3

Are these expanded to 90 lbs each set?

Accepted Answer

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.

Question 4

Is this one not expandable? If not will you be selling the pro expandable block on Amazon?

Accepted Answer

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!
