Fall is officially in full swing: pumpkin spice lattes abound, Halloween is over, and holiday shopping has begun. Whether you like to take advantage of the cooler temps to go for a run outside or use them as an excuse to hit the gym, working out is a perfect way to channel the back-to-business vibes of the season. And on the days when you do manage to get to the gym for a solid workout, we’re big fans of commemorating the occasion with a well-deserved social media flex – or a real-talk selfie with a gym-related caption that acknowledges how hard you worked to make a sweat session happen that day.

But as everyone knows, half of what makes a post is the caption. Sometimes, those juicy workout endorphins offer up a stroke of genius. Other times, your brain might be exhausted from the intense CrossFit workout, cycling class, or strength-training session you just put in. In that case, it can be tough to figure out what to say to go along with your sweaty selfie. So we came up with a long list of gym Instagram captions to help inspire you, whether you’re looking for something funny, empowering, or a little cheeky.

Consider your next Instagram or TikTok post a way to savor the good feelings and health benefits exercise can bring – and if a bunch of likes and nice comments roll in (thanks to one of these clever workout captions), that’s just an added bonus.
