Find a Physical Activity You Actually Enjoy — That's the Only Sustainable Plan

The best exercise program is the one you actually do. If you dread the gym, you'll stop going — willpower has a shelf life. The most important factor in long-term fitness is consistency, and consistency comes from enjoyment, not obligation. Try dancing, swimming, hiking, martial arts, rock climbing, cycling, or pickup basketball. It doesn't have to look like what fitness influencers promote. If you enjoy it, you'll do it for years. That beats any optimal program you quit after six weeks.
