I got expanders for my second set. My first set of 540cc took about a month to recover but I was tight in the pectoral area because mine are under the muscle. When I say a month, I was functioning after a day, at the gym in a week (mild cardio) ... but aware for a month. It made me more sensitive. When I got expanders and went up to 850, the pockets stretched but the recovery was incredible. Days. They were in my way so I had to learn to live with them, they were heavy so I had to adjust, my traps were tight, but no major pain.
However, a word of advice I learned from a dancer, do not work your chest at the gym if you have implants. The pecs will push the boobs to the side.
