Well i can already give you a feedback because I did HLM training this style the last 2 years.
I personally did sets across. So same weight for all working sets. The weight was chosen that the last rep of the last set was the last possible one (perhaps one grinder left).
1.session 3x5 4min rest
2,session 2x15 1 min rest
3.session 3x8-10 2min rest
I did 2 sessions the week. So a full rotation lasted 10 days. Then repeated with more weight or reps.
This went good until each day was rotated about 5 times. This usully meant a increase about 5kg per exercise.
Then I switched to only one heavy working set per day. (So max weight day for 5Â´s then 15Â´s then 10Â´s rpeeat)
This usually got me a added 2.5-5kg increase. But not in all exerices.
Were I messed up the whole thing in following is diet,the heavy day and transition periods.
Goin near failure on lighter sets is a whole different animal than on lower rep sets. I always had trouble progressing on the heavy day because on starting too heavy.
In the transition periods I was too proud to take 75%of of each day and start ramping up to the top weights because that would have lasted quite long when done for each day and I didnÂ´t wanted to be far away from my weight so long.
Also remember that the sets across are always lighter than your rpm for that zone.
So my ramp up weeks got shortended and I didnÂ´t progressed.
Then i played arounf with H/L days but never got the response when doing a simple HLM template.
Worrying about that the light (2x15) and medium (3x10)days are too light is probalby unnecessary. When coming to the heavy 3x3-5 day the weight is nevertheless about 85-90%of 1rpm. Thats heavy enough for strength gains anyway and spur progress on the other days.
