If your implants were inserted under your breast tissue on top of
your chest muscles via incisions in the fold under your breasts or near your armpit, the milk ducts should not be affected and you should be able to breastfeed.

muscles (delts, pecs, and triceps) 3 times per week
via chest press, vertical press, dips, and incline press.
