When I kb swing I have to use a wide stance. I feel like the wide stance activates semimembranosis and semitendonosis more than biceps femoris. See, my problem is I want to activate biceps femoris in its hip extension function because I want to run fast. I wish there was a way to do explosive KB swings with a narrow stance.
Does the wide stance effect the biceps femoris or medial muscles of the posterior chain more?
Should I view the explosive KB swing as a purely glute activation exercise for my purpose of running fast and use other exercises specific to hip extension instead of the KB swing?
what would happen if I held a dumbell in each hand using a narrow stance and did a hip hinge similar to the KB swing? Do you think that would work for hitting biceps femoris?
sorry this isn’t really a powerlifting post. Running is a single leg movement and most of you guys don’t believe in single leg stuff. You guys are all about RFP though and that parallels sprinting.
