The SSF Mission
Bros know that weights are for them. You deserve to feel strong too.
We are for women who sometimes feel too tired or overwhelmed to work out.
We provide high-touch semi-private personal training and at-home workouts so you don’t have to feel guilty for taking time away from your family as you get into better shape.
Unlike similar companies, we keep our sessions very small and private making us a great place to build up your confidence without the crowd.
Your sessions are designed to teach you how to move while building strength and holistically achieving your goals. You'll get help finding the appropriate challenge level to get the best results while focusing on your form.
In other words, we'll build a sustainable plan for your fitness.
Core Service Values
Simple Solutions' purpose is to provide you with simple and effective exercise programs so you can feel strong and confident.
We're committed to remaining a safe space for our clients to strength train. You won't find any diet talk, mirrors, or supplements at the studio. The money isn't worth it to us, your comfort is.
Company Core Values:
- Simple - "Advanced" programs and complicated processes aren't better. People use them to trick and confuse people. What matters is that it works and people understand it.
- Effective - Does it work well in its current context? Things change, is it aligned with current goals and values?
- Science-based - Keep an open mind. Observe. Gather information. Can you test it? Science gives you averages, how can we apply general findings to this context? Test again. Change. Observe.
- We're data-led not data-driven. Let data act as a check on your intuition.
- Have the goals and data been framed correctly?
- Don’t compare a mile time on the grass to one on concrete.
- Optimal Challenge - We all have the skills and motivation to grow. Remove restraining forces. Channel sparks into a flame with the help of the right Sherpa.
- Healthy Skepticism - Try to understand why something works so you can figure out if there’s a better way to accomplish it.
Whatever your version of happiness is, you deserve that. As busy as you are, you've got to do this for yourself.
