If you want to gain muscle mass, then the most correct way is to workout in the gym. With proper nutrition and prolonged sleep for 3 months you can gain 5 kg of weight, but it is far from the fact that these will be only muscles. You can try to use some kind of sports nutrition at this time, for example, when gaining muscle mass growth hormone is extremely effective. It will help burn excess fat, gain more muscle and make the body more prominent. However, before taking these drugs, you still need to consult with specialists, for example, you can contact the Turkish company pharmaHGH for this, you can easily find it in Google.
I stretch 30 mins everyday, yoga 30 mins 3 days a week, weight training 30 mins 2 days a week. I also work at a dance studio so maybe an hour of salsa maybe 3 times a week. For my diet I like to load up on carbs in the morning and protein in the evening. I don’t try to stay away from anything really. If I want cake I eat cake. The most important thing to me is listening to my body. Making sure not to overeat or work out when I don’t feel well (during shark week).
