Why Train with a Group?
Training with a group helps you stay motivated, accountable, and consistent. Whether you're chasing a PR or just trying to get out the door, showing up with others creates a powerful sense of community. You'll push harder, learn from others, and have more fun along the way. Group training can turn a solo grind into something you genuinely look forward to each week!
