Optimization of the cutters and rakers are the key.
The chain parameters used for bucking are not the same as that used for milling.
For example, you can be MUCH more aggressive with lowering rakers because the chance of saw kickback in a mill is NIL.
Rakers are best dealt with using the Progressive raker depth method.
A brief description is

My experience in fixing and maintaining other peoples saws is that raker depths are one of the poorest understood aspects of chains
The Top plate cutting angle (TPCA) can also be more aggressive. NB TPCA is different to the Top plate filing angle which is nominally 10º on milling chains.
There are no single set of optimum parameters as it depends on saw power, wood type, wood width. On large Cedar on the mac I would start with a Raker depth angle setting of around 7º and a TPCA of 45º and vary it from there.
For someone that has these problems then milling on your knees is probably not a good idea either and its far better to be standing up.
A remote throttle will negate the need for a finger on the throttle - it also will prevent the development of white finger.
Higher up handles on the mill will reduce the need to bend over.
Compare the height of the handles on a standard Granberg (bottom) with the height of the handles on my mill (top)

This arrangement allow for a working stance that is more upright and has the operators arms much closer together.
I'm not pushing with my arms - I'm leaning on the wrap handle with my left leg and as the MC throttle used here is lockable, this frees up both arms to add wedges.
This means no stopping - just constant pressure on the mill throughout the cut which improves the finish.

If a winch is used then that too needs to be up higher.
A extra pulley down near the mill rails redirecting the winch cable uptake to the winch high up on the inboard mill vertical is one solution
Will Malloff's approach is completely different.
Note how the winch able arrangement generates a force directly in line with the cut.
