I know I have low fitness levels, which is why I’m trying to improve on it via cycling. The issues arise when I’m left with very little energy and motivation to do anything post workout due to not knowing how to recover or what food/how much food I need so that I’m not binging on food that will be counterproductive to my workout.
I’m 23 and ~370lb if that helps.
Also to answer the “endurance” question: any time I’m on my bike for an hour+ or 20mi+ (whichever comes first).
