Do you want to know more about us?


Stacey started her fitness training in Spearfish at Downtown Gym the spring of 2013, learning all she could before she ventured out on her own.  New Heart Fitness was actually born in “Neuharth’s” garage with 2 clients (the neighbors). Then, in November of 2014 it was time to move to town and expand with new equipment and new options for the people of Belle Fourche.  This small personal training studio served well for strictly personal training and small group fitness. Exactly three years later another expansion to our current location came with more new equipment, larger space, improved bathroom and shower facilities, gym memberships available and new trainers joined the team.
