Why we run strength on four-week blocks

The block system we use in Powerbuild is not about novelty. It is about giving a load long enough to teach you something before it changes.

Most strength programmes written for studios run on weekly progression. Add weight every week, plateau, reset, repeat. We do not run our Powerbuild classes that way. We run them on four-week blocks, and the reason is simple: a load needs long enough to teach you something before it changes.

A four-week block has one primary lift and two accessory lifts. The primary lift moves from three sets of six at a moderate load in week one, to five sets of three at a heavier load in week four. The accessory lifts stay roughly constant. By the end of the fourth week you have touched the primary lift twelve times. That is enough for a coach to see whether your start position is holding under load, whether your bar path is consistent, and whether the load you picked in week one was the right one.

At the end of the block we reset. The next block picks a different primary lift, or the same lift with a different rep range. We do not test one-rep maxes in class. We do not program amraps in the final week. The block ends, we review the whiteboard with you, and we start again.

The thing this system gives you that weekly progression does not is patience. Most members who come to Powerbuild from a self-coached background are used to adding load every session. They stall at week three because they have jumped too fast, and they read the stall as a sign the programme is not working. The block system builds in the stall. Week three is supposed to feel heavy. Week four is supposed to feel heavier. The reset is where you find out what you actually gained.

If you are considering Powerbuild, the thing to know is that we ask for a four-week commitment at the start. You can book a single class as a trial but the programme only makes sense across the full block. The first week of every block is open to new members. Talk to reception about when the next block starts.
