The push-pull method is actually easy to do with a bit of practice and assuming your AFB has a fibreglass back and belly there isn't much chance of damaging the bow as an AFB limb is torsionally more rigid than a recurve limb. It is worth learning to do as a bowstinger is just something else to lose or forget. All set for a day's archery but you can't use your bow because you left the bowstringer at home
Personally I wouldn't equate it with being overbowed as it is more a matter of technique than strength.
My technique is to firmly grasp the bow limb where it meets the riser with my left hand, the lower limb tip braced into the inner arch of my left foot. As you pull towards you with the left hand push the right hand away from you while sliding the string loop upwards and onto the nock. For me it is more pull than push. Check both loops are seated firmly into the nocks. Doing it this way allows you to easily adjust brace height on the course. Just be confident with it - if you treat the bow like some delicate wee thing it'll hurt you
