Holy shit. I snapped my achilles tendon 6 weeks ago, had the surgery 5 weeks ago and have been in the gym 6x/week since then. My legs look like complete shit (moreso than usual). Nobody told me that I had to stay in bed! I was cleared for anything "non weight bearing", so I took that to mean bench, dips, anything seated, pull-ups, etc).
I just got out of the cast this morning and my calf is something to weep at. Holy shit, my muscle-building genetics are shit, but I am world-class in atrophy. I am in a boot now and I am cleared to walk (in the boot) and start PT on Monday.
Why was your recovery so conservative?
