Great call on doing Kilimanjaro! I did it in January 2023 and it was one of the most amazing experience of my life.
I prepared by doing some multiple days hike and doing cardio like running, stairs, walking, rucking. Spend time on your legs. Spend time outside.
For strength, I did 531. Strength training for mountaineering is GPP but legs, core, back and shoulders/traps are still important. Even arms if you hike with poles. But seeing your numbers, you are more than strong enough.
One thing I would do if I would do it again is train my stomach. Altitude fucks with your digestion. I would train it by eating before, during and/or right after some cardio activities. I would eat often when my heart rate is elevated. RHR over 4000 meters was around 90 bpm for me.
You can see details of my experience here.
When are you planning to do it?
