I typically have three leg workouts I rotate and on a MWF training days, end up hitting legs three times over two weeks. The workouts are shorter but intense, each workout has a major move for quads (squats, leg press, lunges) and hams (leg curls, stiff leg deads, hip thrusters)

I'll follow the bigger move with a burnout set like sissy squats or split squats for quads, and kettlebell swings for hams

I've only ever worked my legs once a week I don't know how people train legs twice a week they must have great recuperation or they are not training intensively enough,I train legs for around 45 minutes heavy with short rests between sets and negatives and rest pause and after that I can barely walk.

Depending on your overall goal (e.g. strength versus hypertrophy) heavy and light split is a good start, but think bigger though, periodise your workouts through a plan
choose a type of periodisation, then draw up the plan but bear in mind there are so many variables
duration of workouts, frequency, strneght vs. hypertrophy, vs. Practice engaging muscles, versus overreach versus deload... rest durations +/- and all the rest....... so many that you could do the same workout exercise selection for weeks on end but play with little variables to really confuse the body and shock it into what you need doing
Dont forget to expand on the tools you use; bands, bodyweight to build mind/muscle, Bloodflow restriction - BFR is amazing when done with leg press/seated/standing for calves and also for quads/hams on leg extension/curl - and if you want to really torture yourself into growth include intraset stretching within say a 4 set BFR set.
Again periodise on the tools (BFR/Bands etc.)

An 8 weeks plan might be something like this:
w1 hit each part 2x per week, focus on mind muscle connection - get that right first
w2 Swell the cells right up. Same as above but add intensifiers (drop sets for example or super sets, take shorter rest times to end up with having more workout in the same or less time
w3, Focus on hypoertrophy workouts aim for 12 rep sets, with more cell swelling techniques, push past barriers - focus on maximising cell swelling/the burn - mechanical dropsets, short rest durations, extended dropsets, giant sets for same muscle group -
w4. Hypertrophy rep ranges again - could be play with volume of workouts, longer workout somewhat by adding extra sets per exercise is an example, or more body parts
W5. You could do a strength week here training once per week, aiming for no lower than 4 reps, longer rest times, really push the intensity here
W6. Strength again but twice per week
W7. Overreach - training twice per week, but also twice per day (am/pm, or lunch/after work) - do strength am, growth pm twice in the week so 4 workouts
w8. active recovery/deload and really rest from the overload but also prepping for next prog/phase - take a load off keep moving, get the muscles worked at least once per week, low intensity, 8 rep sets, dont go past failure

i split leg workouts. there is a little bit of cross over, you use some hamstrings in your quad workout and you use some quads in your hamstring workout, but i have quad dominant days and hamstring dominant days. that way i am really able to target and focused on developing each muscle to its fullest. this way has worked really well for me.

you will end up doing some movements on both days, but the focus of where it hits the leg changes depending on foot position, like with leg press. high and wide stance for hamstrings, and a lower closer stance for quads.

neither day is a "light" day. both are balls to the wall. i have heard of guys (Dusty Hanshaw comes to mind) whose legs really lag behind doing 3 leg workouts a week, 1 quad day, 1 hamstring day, and a combined day that is more about a pump and bringing blood to the muscle.

I was reading an article the other day in men's journal or men's health or sum shit but they talkn bout your supposed to work every body part twice a week to increase the growth. After you workout your muscles repair themselves and stop growing after 48 hours. So basically if you want continual maximum growth work every body part twice a week. I know everybody has they own routine and beliefs but I'm just tellin you wat was said and scientifically proven. If you want constant growth hit them after 48 hours brother.

Knee extensions and ham curls for warm ups, plus stiff-leg dead lifts with bar to 95 lbs, then increase weight by 50-70 pounds each time. Rep range 20-25 with the medium to light weight works too, especially with the squats. I've been on an eod compound lift regimen mixing in legs, calves and forearms, along with some back and delts...lunges are good too post work out...

I see the squats and straight leg deadlifts making a difference, too, even with 5-6 reps with heavy weight...

ive never split quads and hammies, but i've done 2x a week for years. Currently doing squats 3x a week. 1 day 3-4 sets 8reps, other 2 days 4-6reps for 3-4 sets then on those days add a few sets extensions and hammies. i'm also deadlifting 2x a week and doing lots of calf work. best my legs have ever been and Im stronger /thicker all around.

I do one day where I go heavy with drop sets, etc. and another day where I work on getting the most blood into the muscle as possible with higher reps,etc. Meadows advocates such workouts and they seem to be working pretty well for me.

I always do legs 2x/wk. One day is focused on quads and the other is focused on ham development. Legs are to demanding to workout both hams and quads fully in just one workout.

I would say most don't train legs enough. Most are so focused on isolating every section of their upper body, they fail to do so with their legs. I think your plan of 2x per week will be fine & effective. Just listen to your body; it'll tell you when to slow down or if you can ramp it up.

That's what I currently do. It seems to work great.
