Prone Leg Curl
 

Prone Leg Curl: Not that the leg curl is not a decent hamstring move, but without the above movements, you will not reach the level of development that you are looking for. I use leg curls from time to time as a pre exhaust move or in a rest pause style fashion. Movements are like the food chain in the jungle. Sprints, RDLs, and GHRs are at the top of the chain when it comes to hamstring movements.
