meet Isma
Isma Terrence is the creator of Powerhaus, a women-only strength training community rooted in power, confidence, and sisterhood.
Her love for fitness began in 2018 with a simple goal: to change how she felt in her body. Like many women, Isma was intimidated by the gym so she started working out in the comfort and safety of her own apartment using free workout apps and a couple of dumbbells and resistance bands. As her strength and confidence grew, so did her desire for more. She wanted heavier weights, a deeper challenge, and fewer limitations. She was falling in love with becoming stronger.
She found her ‘third space’ at her local gym. What she gained from going to the gym went far beyond muscle. Through the routine and program of lifting, she learned discipline, mental resilience, and how to work through hard things. Strength training became not just physical, but deeply personal.
Along the way, Isma also became a certified personal trainer and cycling instructor, blending her love of music with movement. For four years, she taught rhythm-driven cycling and discovered how powerful music and community can be in pushing people through discomfort, especially in a modality she did not naturally enjoy - cardio. Thus, Powerhaus was born from a deeply personal need - wanting that same community in strength training, an exercise modality that was often a very isolated and individual experience.
Powerhaus is a women-only strength training experience designed for women who know lifting is important but may not know where to start or simply do not want to do it alone. She created Powerhaus to remove intimidation, normalize starting where you are, and introduce women to heavier weights in a supportive, confidence-building environment whether that be through her self-taught classes, PWR HOUR, or taking classes with her friends, sisters, and fitness community.
