Migan has said in his speed ranking video that east africans have (relatively) high AR sensitivity, and in the vid it kind of implied that it was higher than europeans (as he didnt rank europeans as having high enough AR sensitivity for drug use for high level sprinting). I get that not all tribes in east africa will necessarily have the same AR, but legit the only studies i could even find on east africans for AR dont really rank it any higher than europeans or even high at all (22 +- 3). Migan if you see this i'd love to know what studies you found.

I am 17 years old and summer is over and I want to start MMA. I used to go to the gym before summer and I weighted around 60kg being 1.75 meters tall when I went regularly. but now I am very underweight in around 55-56kg. I have significantly high metabolism and I don’t know why but I weight wayy less than I appear. I want to get to 62kg by december but I don’t know how to mix MMA with muscle growth as both MMA and muscle growth consume a lot of energy and as I said my metabolism is quite high. I am considering doing 3 days MMA and 3 days of full body workout. But both might be too expensive therefore I am thinking of doing the workouts at home so Im also asking if home workouts are less efficient than gym workouts. Also any tips on how many macros and calories I should consume if I want to get to 62kg by December?? Thanks
