As someone who is trying to lose weight and get fit, I have been wondering if it's important to keep track of my progress over time. I have heard of people measuring their body fat, taking before and after photos, and even using measuring tape to track changes in their waistline. However, I'm not sure if all of this is really necessary. I don't want to spend a lot of time recording measurements and stats if it's not going to make a big difference in my overall success. So, how important is it to keep track of progress over time by recording body measurements or similar methods? Will it really help me stay motivated and achieve my fitness goals? Or can I just rely on how I feel and my overall progress in the gym?
