“if you think about powerlifting It's tricky because we're about to run some loops on your brain here so technically you have Force production which is in the case of lifting it is one rep max so it's the most amount of weight you can lift one time period not repetitions not how many times you can do it not how fast you can do it just what can you get up and the sport of powerlifting like what Lane does it is three exercises know the deadlift bench and the squat and is how much weight can you lift one time you get a couple of tries at it but it's that's effective what it is right so it's really an expression of pure strength it's not really an expression of power at all because the speed component is very poor in fact the deadlift can take as long as you want it doesn't matter did you get it up or did you not squat Etc”

“Gregor siki just published a paper this week in Journal of physiology a blue ribbon journal in our field right the high as you get and this was actually looking specifically at single fiber contractile function changes with aging and the data here are extraordinarily clear have been a long run you see very little loss of function in cro fibers through aging regardless of exercise or not.”
Main Takeaways:

“you see a dramatic reduction in fast twitch fibers and you actually don't see a drop of power and so there's nothing internal to the muscle fiber that's going down so another way to say this is if you take the problem it's the fiber size the atrophy of fast twitch fibers is the almost exclusive the problem with aging in muscle you have got to maintain fast twitch fiber sizes.”
Main Takeaways:

“you can imagine like a squat rack and you raise the arms of the rack yep yep and you have safety pins that run horizontal perpendicular to the ground right y so instead of putting the bar on top of those y you put the bar below them and so you just lift up against the rack and nothing moves and so you can set your position whether you're putting it behind your neck for a squat whether you're putting a bench below it and you just push up on those”
Main Takeaways:
- Isometric exercises involve static muscle contractions without joint movement.
- Setting up for isometric exercises in a squat rack involves adjusting the safety pins to prevent the bar from moving.
- Isometric training can be adapted for different exercises by changing the bar's position relative to the body.

“the advantage is you have less degrees of freedom, less moving parts so if I get you in a position say in a squat and your spine looks good and everything looks good there's a very low likelihood you're going to get out of position if I ask you to do a a back squat is extraordinarily complicated”
Main Takeaways:
- Isometric exercises reduce the degrees of freedom, minimizing movement and potential for injury.
