What benefit is decline on a treadmill?

[Treadmill Review Guru]

Good question.

[Matthew - Guru Team]

Decline training changes up the variables so you can target different muscle groups on a treadmill. Working uphill targets the posterior muscles including the glutes, hamstrings and calves. Walking downhill engages more of the anterior muscles including quads, hip flexors, and knees. While it isn’t necessary to train for long distances downhill, decreasing the incline can break up the monotony of a routine, provide a nice recovery option, and strengthen the anterior muscles as well.
