Romanian or stiff-leg deadlifts with a band are excellent for "grooving" the hip hinge pattern and waking up your glutes and hamstrings before deadlifting.
Use this exercise as part of a warm-up for 2-4 sets of 10-20 reps. Or use it as a high-rep finisher. Time how long it takes you to complete 100 reps and then try to beat your time in the next workout.
Ever had one of those days where you just couldn't get into the flow of your workout? Or worse yet, you don't even make it to the gym? It's happened to all of us before. The mind is willing, but the body just isn't ready (or vice versa).
