[jelling]

One thing that might help with the leaning: get a standing desk with a horizontal cross bar. This gives you another position where you can put one foot up and prop yourself backwards from the desk.

The leaning itself is a function of TimeStanding > CurrentStrength. Even if the horizontal bar reduces 50% of the load, you'll still end up doing more standing reps/work if you have a cheater bar. Eventually you may not need it at all, but it's also great for keeping the desk from wobbling.

UpLift's commercial line has them and the extra cost is well worth it, imho.
