@retr0id is trying to do a one arm chinup (OAC). Will I be able to do one before him?

Today I did a 1rm of +72% bodyweight.

In 2019 Jul I did a 1rm of 79% bodyweight but was unable to OAC. I tried a variety of exercises to approach the OAC around this time but never achieved it.
- One arm lat pulldown at 69% bw for 4 reps
- OAC with 4% bw assistance (weight on a rope)
- OAC starting halfway up
- One arm lockoff for 15s
- One arm shoulder retraction for 8 reps

In 2020 I did a 1rm of 88% bw but was still unable to OAC.

I was a 3 min walk from the gym over the last year while regaining my strength, but just moved and am now a 13 min walk away.

The deadline will be extended until one of us achieves it, or it will N/A at the end of 2027.
