Have you tried taking protein shakes cause they help a lot. Also if you go to the gym do very limited amount of aerobic exercise like running long distances cause itll waste energy. If you focus on heavy weights then youre more likely to gain muscle coz high intensity is more challenging for muscles
I have searched the internet but you never understand anything about it... especially because it’s full of contrasting opinions. Any tips? Thanks
Just go regularly to the gym ( or while there is corona do some work out at home). I recommend doing the three most effective exercises regularly (!) SQUAD, DEADLIFT and BENCH PRESS. Make a Plan for a Cycle of 6 weeks an example: week one you start with Squad 20kg, deadlift 30kg and Bench 20kg each 5 reps and 5 sets. Next week you add 2,5 kg and so on and in the end of the 6 week cycle you do a max out. You do a warm up (NEVER SKIP THE WARM UP) and than for every round you add 2,5 kg to your set and you only do one rep and you see how far you can go. The next Cyle of 6 weeks you start with 22,5 kg and repeat. Muscles dont grow over night it needs time and consistency. And you have to eat very clean and well! Loads of vegetables and proteins (Tofu, Chicken etc) Protein Shakes are pure ******** and not healthy!
You workout, surprising right? Then, you eat in a caloric surplus - 200 to 400 above maintenance calories should suffice. Progressive overload is key as well. Also, you rest.
