Find a place full of people who enjoy working hard, who do “things like this”, and immerse yourself in that community. Everyone is coming in with different goals and fitness levels, but at the heart of it, they wouldn’t be here if they didn’t value hard work. It’s inspiring and fun, at the same time. And being around people like that helps you grow.
If you have a goal, share it with classmates and coaches, and use them to hold yourself accountable. Then, set about putting in the work to make it happen. A little bit each day, each week, each month. Make that work a non-negotiable part of your life, and avoid the urge to seek out a special program or short cut, because it doesn’t exist. You just need to show up and work as hard you can.
