My wife took Karate for years and now majorly struggles with proper heavy squat form because she has the horse stance ingrained in her movement patterns.

Those are quads, retard.

no it is better for knees than sqats and builds control and increases balance helps posture when done correctly. is very good. to find the stance put your feet together, the move them out by sliding your toes arart then you heals twice and squat down, try to keep your back straight and hold for longer than you think possible, don't forget to strech otherwise cramps are garenteed when you start

>>35280084
they're quints if you squints

>>35280084

Yes, it would probably be considered isometrics as you're holding a single position with tension. However you're likely not contracting with maximal force, so they're less effective than other forms of isometric hold or other static positions.

However, the issue with all isometrics is that generally, they only strength the range of motion and associated tissues within 15 or so degrees on either side of that position at the joint. In other words, you'll be great at holding horse stance, and not that great at much else. It's not dynamic strength through a range of motion: it's specific strength in one range of motion.

Also, unless you continue to weight the position and then hold for consistent time, you'll start training endurance rather than strength. If I progressed from 15sec holds to 15sec holds with an extra 30kg, that would increase strength in that position. If I just get to say 90sec hold time, I'd gain some strength, but I would mainly be training endurance.

Thus I would not recommend using these unless you train specifically for a sport or art that demands it. You're wasting time that could be better invested into other exercises entirely.
