Hey! Arm strength has been a hard thing for me throughout my life. My haphazard goal for the last several years has been to do 1 strict pull-up. This has eluded me yet.
The biggest gains I have seen are due to the max strength workout we have been using for ice climbing training. This includes 1 arm lock offs and 1 arm hangs. These I do on a pulley system connected by carabiners to kettle bells. These kettle bells offset my weight and allow me to do the full movement. I have also used this to help me do my pull-ups.
I also started using a habit adjuster. My goal is to do 2 pushups each morning right after I wake up. Getting at least 2 in is a great start to doing more movements. And doing these does help change my neuromuscular makeup. I like Diana’s suggestion to work on a pull-up each time I pass under the pull-up bar. I am going to try that in hopes of hitting that 1 pull up soon!
