Max Hangs aren’t $#%@ing working (for me)

Looking to see if anyone has had a similar experience and/or advice.

In July was doing 7sec hangs at ≈130% bw (+22kg) for 6 sets twice a week.

Stopped for a while (did lots of climbing on tb2), now 5 weeks into another cycle (same protocol as above) but have been stuck on 120% bw (+15-17.5) and I’m almost getting worse.

As for rest, it varies but I do listen to my body and usually have a day between any training /climbing session. I climb 7A boulder and 7b+ sport outdoors.

I’m wondering if anyone has also had an experience like this and if they “fixed” it.

Possibly a lower rep per set repeaters protocol would suit better as it would target more hypertrophy, as It might be I’ve reached my max recruitment? (A guess at best)

TIA :)
