Hip Thruster Update

Hi fitness friends!

It’s been just over a year since I launched the Hip Thruster unit, so I felt that an update was in order. Originally, I assumed that Hip Thrusters would mostly be purchased by women seeking better butts from their own homes, but there are now Hip Thruster units around the world in gyms ranging from dingy garages to pro sports team training facilities.

Are the Hamstrings Really Primarily Fast-Twitch?

For the past 20 years or so, I’ve been reading strength & conditioning articles claiming that the hamstrings are primarily composed of fast-twitch fibers. I can recall repeating this same information to lifting partners way back in the day. In ten minutes, with a quick Google search, I found articles from plenty of well respected individuals in the strength training community claiming that hamstrings are mostly fast-twitch (hundreds of other articles claiming the same exist, but I chose to link authors or sites I’m familiar with), including:
