Heavy structural lifts deliver more balance than “stability” and balance exercises: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3885846/ .
That's right. Lifting weights gives you better balance than showy balance exercises.
Every time that a heavy deadlift program is stacked up against bosu-yoga-side-band-single-cross-body complex press-pull skibbity scoot nonsense, the structural lifts prevail.
BUT, fitness popularizers will showcase exercises like these to excite an audience. It’s a put on. The craziest balance exercises I’ve ever been capable of performing was when I didn't even practice balance per se. I just got incredible balance by getting deep layers of muscle very strong. High level strength athletes who perform NO silly balance drills put my balance to shame. Elite powerlifters have far better balance than a tv celebrity trainer simply because they are so powerful (the same muscle fibers which govern reaction/balance). You'll notice that weak people have terrible balance no matter how much they practice balancing; and strong people have good to great balance even if they practice no balancing.
Nonetheless, if you want to try something different, here are some balance variants (videos here: https://www.instagram.com/p/B4MxQ8cjJvK/) whose primary value is to keep the program from feeling stale. In the end, however, just get strong and your balance will improve.
