When you start your journey with a mentor, things might not feel as you expected.
Probably, In starting you might feel that I am not learning anything or I am not learning what I have expected to learn.
I would suggest you something, just have patience, your mentor knows what he/she is doing.
Have faith in your choice, and just do whatsoever your Mentor/Guru is suggesting you to do.
If you are doubting then soon you will be off track.
For having a fit body, you are not going to start heavyweight from the first day of the workout.
There is a lot to understand before your body is ready to lift heavy weights – Your eating habit, your diet, your mindset, and much more.
Have Faith.
