Right now this is where I'm at for Manna training: https://www.youtube.com/watch?v=gjK_mQ0l89Q (my apologies for the language, I was very excited). As you can see, I definitely still need strength and balance in that position, but it's a work in progress.
Currently for Manna training, I'm working MSH for 10 minutes (Coach Sommer's recommendation) 3x a week. An average day would be ~8 sets of 10s MSH up on first knuckle with legs not in contact with hips, and ~60s of rest. I work pike and pancake mobility and compression 3x a week. I follow a full body routine 3x a week, as well. I'm 17, 155lb/70.5kg, and 5'10/178cm. I formerly trained under Foundation, but no longer. I realize that is the advice I am likely to get, but is there anything else? I also include German Hangs in my training, and am going to implement "weighted shoulder flex pulls" soon.
For those who have experience training Manna or the knowledge behind what generally works, what would you suggest? And how close am I to the actual Manna? If you have any questions, I will be glad to answer them. Thank you!
