Americans are still sticking to their fitness goals, says new summer study

July 8, 2025

According to a new nationwide survey by Planet Fitness, 70% of Americans who set a fitness-related resolution are still on track with their goals. Whether they’ve been going strong since January 1st or regrouping after a few hiccups, the resolution drop-off is much lower than most people expect. The new online survey, conducted by Wired Research, interviewed 1,000 nationally representative Americans ages 18 and over.

The study also discovered that Gen Z and Millennials are extremely resolution-committed, with over 80% saying they keep the momentum going. The study also asked Americans about their willingness to exercise in summer heat, of which 76% responded they would rather put themselves through an uncomfortable situation (think time share presentation or awkward family dinner) than to exercise outside in 100+ degree weather.
