Tracking your workouts is important for debugging later - if you're not getting the results you want, how can you figure out the issue if you don't know what you've been doing?

If your goal is "general health" and you're doing okay, you're lucky (or you should set harder / more specific goals!) But as an example, I thought I was eating well, but when I started tracking my calories for a few months, I realized I had underestimated my daily calorie intake by about 400 calories, and I was still eating way too many carbs for what I considered to be a "low-carb" diet.

I'm also on Fitocracy (was using spreadsheets before) to track weightlifting - tracking is a necessity for lifting IMO.

It took me about half a year of lifting to get where I wanted to be, and tracking was instrumental in achieving that. But now it's all just maintenance, so why should I track? Some people approach it like a sport (that you want to continue to get better at) and some approach it like exercise (to maintain a level of fitness) – both seem perfectly fine to me.

I am not familiar with Fitocracy but it seems to be getting much love here. Part of my dislike for tracking and measuring fitness might come from my experience with cumbersome apps that make the process a pain. I used Fitness Buddy for a period, and found it way to complicated and in-depth to make tracking how much weight I lifted and the reps quickly between exercises. I'll give Fitocracy a shot, and see if I change my mind.

As a side note, I do like tracking how much I walk, but not for debugging, but for motivation. I'd like to hit a 100 miles before the end of the year just by walking at lunch, but for no other reason that personal pride I guess.

Hi, one of the cofounders behind Fitocracy here.

While much of the discussion here is focused on tracking activity, I want to mention that we at Fitocracy consider tracking secondary to the social experience the app and site provide. We believe that the key to long term success isn't about numbers on a screen but rather, making fitness a part of your identity and every day life through spending time with people and communities just like you. I highly recommend you check out the social aspects of the experience if you download the app :)

I just carry a small notebook with me to the gym. I note the reps and weight, and any subjective notes about what worked, what didn't, and what to aim for next time.

Takes a few seconds to fill out in between reps.

I'm sure there are useful, simple apps, but you don't need an app to track.

As others mentioned, tracking lets you make sure you're increasing your lifts. I never progressed consistently until I started tracking, and slightly increasing each time.
