Programming critique to fix slow progress towards muscle-up

[verronney]

I've been training calisthenics just short of 1.5 years. I'm aiming for a strict muscle-up, but my progress is quite slow. I just recently cleared my first green+purple band assisted muscle-up. Could you please help me with critique on my current programming?

I train 3 days per week, following a 4 day routine, with continuous progressive overload. I start every training day with 30 minutes warm-up and mobility.

• 3x25s R+L 1 arm hang

• 3x8 toes to bar

Training 3 days per week is what works for me to fit into the life/training/work puzzle.

I'm 43. 166 cm. 84 kg. Before training calisthenics I did powerlifting, following a 5/3/1 program.

At the moment, I'm in a deload week, so I figured it'd be perfect timing for a bit of feedback on my routine.

Thank you in advance!
