Back at the gym and my implants MOVE when I flex. Push ups make them flatten and jump upwards. Is something coming loose?

Long time lurker, first post, mildly freaking out. Surgery was mid January, 320cc dual plane (partly under the muscle), textbook recovery, surgeon cleared me for full training at six weeks and I've spent two months slowly building back up. Lifting is my whole personality, this surgery took a year of deciding partly BECAUSE of the gym.

Tonight I'm warming up with push ups in front of the mirror and I catch it: every rep, both breasts flatten across the top and sort of hop upwards and outwards, then drop back when I relax. Left one does it more. It's not painful, not even uncomfortable, it just looks WRONG, like there's a mechanism under there. Did some flexing at home in the bathroom (do not recommend, worse lighting, more panic) and yep, if I tense my chest hard they visibly distort and shift.

Nobody mentioned this. Not at either consult, not in the discharge notes, not in a single one of the nine million recovery vlogs I watched. Is the implant coming away from something? Have I torn it loose by going back too hard? I've got a review booked anyway but it's three weeks out and I need to either calm down or panic properly.

Breathe. What you're describing has a name, it came up at my six week check when I demonstrated the exact same mirror discovery to my surgeon and she said "ah yes, animation" like I'd shown her a paper cut. Mine flatten and jump on the last reps of push ups, wall presses, even pushing a heavy door. Nearly three years... wait, no, coming up on a year and a half now, and it has never once hurt, changed how they look at rest, or got worse.

Honestly these days I only notice it in two situations: sports bra fittings and showing people who don't believe me. It becomes a party trick or a crisis, and you get to pick.

Adding the comparison point since my setup is the other one: mine went over the muscle (my tissue could cover it, surgeon's call), and I get none of this, I can flex away like a bodybuilder and nothing moves that shouldn't. BUT, and this was explained to me at the time, the trade is that under-the-muscle placement earns its keep in other ways, extra padding over the top edge being the big one. My friend with the same implants as me over the muscle can see a faint edge when she leans forward. Every placement is picking which imperfection you can live with, which nobody puts on the mood board.

Also want to gently flag the phrase "coming loose" because I had the same theory once: there's nothing to come loose FROM. It's not bolted to anything. It sits in a pocket. The moving thing is your muscle doing the moving, not the implant escaping.

Discovered mine mid-plank in a pilates class, glanced down and thought I was having some kind of event. Resident cautionary tale checking in to say the panic is universal and apparently the warning is in none of the brochures.

Question for the knowledgeable while we have this thread open: does it get WORSE the more you train? Meg lifts properly, I just do pilates, but if a bigger stronger chest muscle means more dramatic hopping, that seems like information the gym girls deserve in advance.

No, and nothing you did in the gym caused it. What you've found is animation deformity, sometimes called flex distortion, and it's the expected mechanical consequence of the placement you chose rather than a complication of your recovery. In dual plane and submuscular placement, the pectoralis major runs over the upper part of the implant. When that muscle contracts, it presses and slides across the implant beneath it, so the upper pole flattens and the breast shifts upwards and outwards, then everything returns when you relax. That's the entire mechanism. Natalie has it exactly right that there's nothing to detach: the implant sits in a pocket, and the movement you're watching is your own muscle working over the top of it. One side showing more than the other is typical too, since muscle bulk and the surgical release are never perfectly symmetrical.

Some honest numbers, because this is genuinely underexplained before surgery: when surgeons examine for it deliberately, some degree of animation is found in most patients with muscle-cover placement, around three quarters in some series. The share who are actually bothered by it day to day is far smaller, most studies put it in the single digits to low teens as a percentage, usually people whose work or training involves visible, repeated chest contraction, so lifters, dancers, and yoga and pilates teachers are overrepresented. EmmaLouise, training makes it more VISIBLE rather than more severe: a stronger, more defined pectoral contracts harder and you also get better at recruiting it, but the anatomy underneath isn't worsening and lifting will not damage the implant or your result. It's also part of a trade, as this forum's placement discussions keep discovering: the same muscle cover softens visible edges and rippling in slimmer tissue, and placement affects other practicalities down the line, which the site's guide to breast implant placement lays out properly. For the genuinely bothered minority, revision to move the implant in front of the muscle exists, sometimes with fat grafting to replace the lost padding, but that's a real operation with its own trade-offs and belongs in a consulting room, not a forum plan.

What animation is NOT: new pain, swelling, hardening, or a change in shape at rest. Any of those deserve a prompt call to your surgeon rather than a three week wait. A flatten-and-return that only appears when you contract, in an otherwise comfortable breast, is the benign version, and your review is the right place to have it confirmed on your own chest.

Update from the far side of the review: surgeon watched my push up demo, said "textbook animation, lovely muscle function actually," and signed me off completely. Deadlifted a small PB last week, implants unbothered, ego repaired.

Follow-ups for the archive: I asked about exercise after breast augmentation rules since I'd been half-wondering if I broke something by loading too early, and she confirmed the cleared-at-six-weeks plan was fine and the animation would have shown up regardless, it was there from surgery, I just hadn't met it in a mirror yet. And sixweekspost is right about the two situations. It did a full appearance at a bra fitting on Saturday and the fitter didn't even blink, apparently I'm not remotely her first mechanism.
