Based on your description, I believe you could be an excellent candidate for Motiva Preservé breast augmentation, particularly because you have well-developed pectoral muscles, exercise regularly, and want a modest, natural-looking enhancement.
With dual-plane placement, part of the implant sits beneath the pectoralis major muscle. This provides additional upper-pole coverage but can cause animation deformity during muscle contraction, even if you avoid direct chest exercises.
Preservé uses a subfascial, muscle-sparing approach, preserving pectoralis muscle function and avoiding muscle-related implant distortion. For someone with your lifestyle, this is a significant advantage.
I would consider Motiva Ergonomix2 Mini 245 cc or Demi 300 cc, depending on your breast base width, desired fullness, and tissue thickness. Both could provide a subtle enhancement without unnecessarily increasing implant volume.
Your concern about visible implant edges and rippling is valid. Subfascial placement does not eliminate these risks, particularly in very lean patients. Therefore, I would carefully assess your upper-pole soft-tissue thickness before confirming the surgical plane.
Subfascial implants do not inevitably sag more than dual-plane implants; long-term breast stability also depends on implant size, tissue quality, and individual anatomy.
My preference would be Preservé with a conservatively sized Ergonomix2 implant, provided you have adequate tissue coverage. If your tissues are extremely thin, dual-plane placement may still be the better option.
