It's also very important that fitness means practicing at 4 points and eating at 6 points, ensuring that you eat less and eat more, and taking as much protein as possible, which will achieve twice the result with half the effort. Of course, if you can eat protein powder, if you think protein powder is unnatural or too expensive, you can try eating eggs and potatoes together. This food combination is the best absorbed in protein, far higher than beef of the same weight.
Finally, I'll give you a suggestion. Ask the coach and how many friends like fitness. They will all have successful experiences and can choose what suits them to try.
I wish you an early training of muscles that men hate and women like!
