I am bit shorter at 5'11" and have had the same issue with the white one above. I now steady the tube with my knee. Left foot on the base and the tube on the inside of the knee cap. Works great that way.
With the check valve now working, I can get to 120 PSI in about 20+ strokes. My main approach is to use the air compressor that gets to about 110. Then I use the pump to get to 125 on up. The first stroke needs to be sharp to get the stem valve open and the hose pressurized. Then it is fairly easy, but with increased pressure, less volume input.
The added benefit is the exercise of the upper body!
