I find that when I add upper body motions to my high horse stance holds that I hold for longer and with the perception of time being that it flys by.
I do a tai chi like arms in and out motion.
Hands together in a prayer position.
The hardest thing is to hold arms out straight parallel to the ground, as in a traditional horse stance.
I’ll do the pushing side to side that Wim Hof can be seen doing, this, and sumo one arm pushes I will count off by military four count.
50 reps generally equals over a minute.
I also do karate blocks in which I flex hard.
Occasionally some other flex.
Another good one is pulling the fists into a tight karate loaded for the punch position.
The creativity and options here are endless.
This practice of combining upper body work with a lower body hold makes it all the more effective.
Like the burpee, this can be the entirety of your training if you find yourself without equipment.
