I found out that I personally have better results or more strength during my training after I had a lot of protein and carbs. Then I feel much stronger. The app helps me to draw connections between how my training goes and what I've eaten, which is really helpful.
I have created recipes for most of the meals I usually have, so it doesn't require a lot of time to log everything. I also start to see results now and that's keeping me motivated.
