I don't feel my legs are lacking but ill kick it up a little ,but again can we comment on the cardio I do 45 on leg day and usually another 45 on calves and bak day also I didn't add that i do abs abs twice a week I switch it up tho and they are not alot of weight, i do cable ball crunches and cable crunches one day then i do decline medicine ball sit ups and decline medicine ball side tosses,abs on me are what usually never are sore and recovery just as fast as my arms and chest but I would like to hear the cardio ideas. I heard different stuff about cardio for everyone.
