Hopping, a plyometric move, has been show to build power which translates to better running at higher speeds.

Six-Week Daily Hopping Program:

Week 1: 5 sets of 10-sec. hopping/50-sec. rest (total hopping: 50 seconds)
Week 2: 6 sets of 10-sec. hopping/40-sec. rest (total hopping: 60 seconds)
Week 3: 8 sets of 10-sec. hopping/30-sec. rest (total hopping: 80 seconds)
Week 4: 10 sets of 10-sec. hopping/20-sec. rest (total hopping: 100 seconds)
Week 5: 15 sets of 10-sec. hopping/10-sec. rest (total hopping: 150 seconds)
Week 6: 15 sets of 10-sec. hopping/10-sec. rest (total hopping: 150 seconds)
