I am a 38-year-old male, however, I look much older, grey hair, balding a bit, grossly poor fitness (overweight), low energy levels, dark circles around my eyes, and the list goes on. What can I do in three months to look much younger and feel healthy?
I am 18 years old, and I am stocky (175 cm and 78 kg). If I go to the gym and do weight lifting, can I be slimmer?
