Here is another set of running specific run movements by our personal trainer Matias.
"Do some Box jumps to get those explosive and fast twitch muscle fibers working. Four to six reps per leg is enough.
Calves are important for running so remember to work them. Calf raises are really good for that. Go for 12-15 reps per leg.
A Swissball Hamstring Curl is an excellent way to strengthen your hamstrings. They're injury prone so remember to strengthen them. Do 6-8 reps.
4 rounds of these 3 movements and your trail running season will be long and prosperous."
