So in our country’s military you are asked to perform a basic fitness test. One of the tests consists of holding yourself in the highest position of a chin up for as long as you can. It is allowed to press your chest against the bar. The test is over when your chin is no longer above the bar. Chalk is allowed and you don’t have to pull yourself up, you stand on a box which is then dragged away under your feet.
My girlfriend wants to take this test again to better her time. Her best ever is 1:30+ minutes. However she had to deal with long periods of being ill and injured and when she took the test last week, she was down to 46 seconds.
She has about 4 weeks to improve her time.
A problem she has is that she doesn’t get her back involved and only feels this exercise in her forearms and biceps.
Do you have any ideas for her to improve her time in this short time?
