Group fitness classes are fun, motivating, and a great way to stay consistent, but if your goal is to reshape your body, build lean muscle, or get stronger, they can only take you so far.
That’s where progressive overload comes in.
Progressive overload is a training principle where you gradually increase the stress placed on your muscles over time, by lifting heavier weights, increasing reps, or improving technique. It’s the only way your body continues to adapt and change.
In contrast, group classes often focus on intensity, variety, and calorie burn. While that can help with general fitness, the workouts are rarely structured to build long-term strength or muscle. You might sweat a lot, but your progress eventually plateaus.
Here’s the truth: if you're using the same weights, doing the same movements, and pushing the same level of effort week after week, your body has no reason to change.
This is exactly why Signature Shape doesn’t miss the mark.
We combine the energy and community of group classes with dedicated Signature Progressive Overload Days, designed specifically to help women build real strength, improve performance, and actually see results. No guesswork. No random workouts. Just a smart, structured system that transforms your body from the inside out.
Because at Signature Shape, we don’t just help you move, we help you evolve.
