i started last year. I had a back pain due to incorrect posture and long sitting. My only goal was to build discipline, i only did cardio plus few chest exercises , went for 6 months, had taken help of trainer as I didn't want to suffer from back injury. I also did mri meanwhile and nothing came out. Due the workout routine my backpain went away. Backpain was the result of my laziness , haha. Unfortunately my discipline broke and from past month i have started again. Now I am focusing on building muscle, so following push pull leg split. Just today installed lyfta app to learn new exercises. In this one year journey I have avoided sweet and packaged products altogether, only ghar ka khana. Lost 8kg in healthy way. Now I have a great physique. My goal for this year is to build muscles and strength. I wish you all the best too. For discipline I would suggest you to just have in mind that you have to gym just go, you will do exercises going there. All the best pal. It's really worth it, its fun, its amazing
