This session was 10 hill reps with a relaxed jog recovery to the bottom before turning straight back round and going again. Drive up the hill, use your arms, shorten your stride and go! Hills are a good form of resistance and strength training. They fire up your quads, hamstrings, glutes and calf muscles. Please let me know what type of running/fitness sessions you would like me to post and I can add them to my weekly routine.
