Hammies are about the only muscle that works two ways.
One it activates and helps with the glute contraction -SLD, RDL, GMS, etc
Two it brings back the lower leg, any leg curl
For happy healthy hammies I recommend both.
For many years I SLDed, GMed and lifted nice weight. When I took up heavy weight throwing and hammer, I developed a injury where the hammie ties into the glute. Was very surprised how my SLD hammie strength was not reflected by my leg curls done for the first time in 20 years.
Yep leg curls and a strange one legged secret exercise (too weird for you guys) fixed it (with lots of massage and physio)
