@coach_mundy_: I’m not answering “what about —-?” Because you can do what you want, when you want. It’s nothing to go learn basic joint actions then apply them into training. - Calves. A bent-knee is not needed. It doesn’t grow the soleus more all while reducing the gastroc. So might as well just stick to a straight leg and work on how deep you take them with pauses. - Quads. Knee extension with a fixed hip will train all quads. But it is not at all practical to never do squats. Use your imagination why - Hamstrings. Seated leg curls are the most ideal curl option for hamstrings. If you do lying, who cares. Mix in hip extension patterns with a straight, fixed knee - Glutes. The glutes, hamstrings, and adductors all extend the hip. So some positions can favor either muscle group more. So reduce the hamstrings contribution for hip extension, you’ll be left with more glutes and adductor Magnus. - Stop skipping adductions. That’s why your thighs don’t touch
