I am the type of individual that looks at myself in the mirror every morning and night briefly to make sure I am not drifting off into an undesirable body shape. Sometimes, this will warrant me exercising a lot. For example, if I run a bit and lift weights over the course of a couple weeks, I notice a very quick increase in muscle mass, which seems counter intuitive to the notion that building muscle takes time.
I do an array of comprehensive exercises and reps for weight training, and my running is intense. However, I notice that in a few weeks, once I reach a threshold, I start gaining lean mass too quickly and excessively, to the point where my shirts that fit quite loosely and are rounded around my back and shoulders. My back and shoulders seem to gain muscle mass the quickest, and I get a v-shape along my lats very quickly.
However, if work creeps up or I have a lot of tasks to do, (I know excuses aren't good) I stop working out. I lose everything in a matter of days. What's the explanation for this?
Just a brief history of me.
Medical: Genetic cause of moderate anemia, type 2 diabetes on my father's side, I am about 5' 9", 160, lean, but have latent insulin resistance (fasting around low 90s)
Diet: clean for the most part, I have a penchant for fried meats, I avoid sweets. I eat a moderate amount of protein, fruits/veggies in every meal.
Sleep: bad, I sleep 5-6 hours on weekdays and 10 on weekends. Inconsistent.
Exercise: Bimodal. Either sedentary or very intense. I try to get in something brief like 30 minutes a day on some days where I'm very busy..but these usually involve things like playing with a soccer ball around my neighbrhood or pushups/pullups..no formal cardio/weight training
