I'm not sure where I'm supposed to be feeling the straddle tuck. They don't seem difficult but I also haven't worked up to mastery yet. The day after I don't feel much soreness in my abs. Any insights?
Also, with the Jefferson Curls, my legs are straight and knees are pushing back (thanks to cues from the Front Split Stretch series). Do these look good enough otherwise? I'm also using a 45lb. bar. Thanks
