Try the spiderman crawl, a lower-body drill that builds mobility.

Assume a pushup position. Now take a big step forward with your right foot and place it outside your right hand. Pause for a few seconds, and then lower your head and chest for a deeper stretch in your thigh muscles. Walk your hands out until you’re once again in a pushup position, and step forward with your left leg. Do 8 to 10 reps on each side
