You may be seeing a few posts that go back to an idea that I'm thinking about that come from Charlie Weingroff's "Lateralizations and Regressions" DVD as I'm working my way through them currently.
One of the messages that struck home was the idea of load.
"If I have a way of lowering system load...you win."
Say you back squat 405lb, but you front squat 225lb. Both are equally hard. If you choose to front squat, you get equal fitness but have almost cut your system load in 1/2. Now you can front squat 225lb but you can only front squat with two 50lb kettlebells held in the rack position. Both are equally tough for you, but if you choose the kettlebell, you have essentially cut system load in 1/2 again. Now, instead of holding the kettlebells in the rack you hold them in a bottom up position and can only hold 25lb kettlebells. Again, equally hard, but you have once again cut the system load in 1/2.
Very interesting concept to keep fitness, but slash system load.
It's up to you to decide how to implement in your own athletes/patients programming, but it is a cool way to manipulate a few variables.
