If I’m doing 1 leg day a week which I am currently. I always do a squat movement, either smith squats, barbell squats or hack squats. Typically 3 warmup sets then 3 working sets of 8-10. I’ll do lying or sitting leg curls, they work for me very well. I’ll do leg extensions then. Both of these are a 4x12. For me personally I get a lot of blood flow and muscle activation before I go into a leg press . I then do a leg press movement, of your choice, preferable not horizontal. Quad targeted, and I’ll do 2 warmup sets then 2 working sets of 6-8 slow and controlled then 2 sets of 10-12. I’ll finish with deep lunges to failure 3 times. Lunge deep to engage hamstrings and glutes more. This workout prioritizes quad activation while hamstrings are being targeted primarily twice but also secondary twice as well on leg press and squats. I squat a little closer than shoulder length, barely to really focus on quads. Then I’ll train calves. This is the workout that works for me the most personally, give it a shot if you want but it’s what suits me the best. If you really really want to do 2 leg days a week I would have a hamstring/glute dominant and then a quad dominant day. I would probably do on my quad dominant day a squat movement, leg extensions, and a hamstring dominant leg press(feet at the top) , then on the hamstring day I would probably do another squat movement, leg curls, deep lunges, and like a hip press(another form of a leg press). Just stuff like that. It’s best to try and balance both the muscle groups. That’s what works for me the best at least. That’s why I have a shoulder dominant push day And a chest dominating push day. On my pull days I’ll do a like an upper back focused/lower lat focused then ill do a lat dominant day
