What's the best way to start doing pull-ups?
Pull-ups seem to be a very difficult exercise for many people. I've worked out consistently for decades, and at 61 years old I typically do 4 sets of 15 wide-grip pull-ups, and 4 sets of 15 close-grip pull-ups, three or four times a week. Sometimes, just for fun I'll wear a belt with a 35 lb weight and do sets of 6. For reference purposes, I'm 5'9" and I typically weigh about 155 lb.
In the photo below I have a total of 90 pounds hanging on the belt. I am only able to to one pull-up with this weight (so far). Most people probably think it's crazy for a 61 year old guy to do these things but that makes it even more satisfying to me ;-) My joints and tendons seem to be able to handle the stress just fine, and I've yet to even experience any soreness from doing these exercises. Maybe it's the fish oil?
