Deadlift and squat are very fundamental in every sport and for your body and your health. Of course, if you will do 1rm deadlift never train you will end up in the bed, with sore back :) your back is fine, just you need more knowledge. I am a personal trainer and Olympic lifting coach. If you won't do deadlifts and squats you will damage your core and back discs. I am a bodybuilder and 99% of people who never do deadlifts and squats end their sports career. Try to listen to my advice, and you will never feel back pain again, only you will have sore muscles.
