Just depends on your core strenght
I've been climbing hard for 6 years. Been in the business for 9 years on the ground. Taking over for my 60 old man. Shoulders hurt from working 2 sections of pole saw after about 3 straight days. Just got to know your body and not push to hard. Your body will get used to the punishment but remember, your not made of titanium!10 years in and I got the best news of my career last week from my physical therapist. She said the neck and shoulder pains are primarily from poor posture. 140% on rotation. Out did the yoga dorks that come she said. 6'2 and 165 lbs. I told her I burn 8000 calories a day and eat 5 sandwhiches + b4 dinner. Then I asked about being skinny and wanting protein shakes. She said NO WAY. That stuffs hard on your kidneys and your fit anyways.
I eat well stretch and swim in the ocean. I asked if my lifestyle is sustainable and she refused to comment......ah crap. Not to many desk jobs around here:eek2:
Posture has changed and I feel like a million bucks. 14hrs a day 8 days a week.
