This is a great superset for the posterior chain: the hamstrings, glutes, and lower back. Without resting between exercises, perform the Romanian deadlift, a sled push and then a sumo deadlift.
Elevate the toes on the Romanian deadlift to better target the hamstrings.
Pushing the sled with a wider leg stance better targets the glutes.
For the sumo deadlift, avoid raising the hips too fast when you lift off the floor. As soon as you pass the knees, snap those hips forward by squeezing the glutes.
Thibs is on a mission. The angry Canadian wants to see the incidence of training stupidity decrease. Are you a "kitchen sink" trainer or coach? Have you misinterpreted the concept of overtraining? If so, duck!
A perfect warm-up virtually ensures a perfect workout, but a poor one will almost certainly ruin what COULD have been a great training experience. Ever wake up dreading the idea of going to the gym, but after getting there, you end up having a great workout? You can thank your warm-up for that.
