Traditionally what we see with a lot of endurance athletes who are new to strength training is an inability to “connect” with the hamstrings and get them to fire during compound movements such as squats & deadlifts. So we like to incorporate some isometric hamstring work initially to help spend some time under tension where you can really engage, move around a little, focus, and find positions that will help to get the hamstrings to come to the party and support our larger movements.
