I just got back into lifting, after taking roughly a year off because i was forced to basically ..

During my time off, i a friend who had seen great results told me his routine

simply 1 muscle during a 8 day period

example:

Monday - chest/forearms + 30-45 mins of cardio
Tuesday- Legs/abs + 30-45 mins of cardio
Wednesday- off
Thursday- bicept/forearms+ 30-45 mins of cardio
Friday- tricepts /abs + 30-45 mins of cardio
Saturday- off
Sunday-shoulders/forearms+ 30-45 mins of cardio
Monday- back /abs + 30-45 mins of cardio
next day - off
repeat

understand the routine? i've been doing it, and the reason i like it is because i want to do cardio with my workouts, i want to lose fat

and its pretty tough to do 2 muscles + cardio all in one session and no time to split , such as cardio in morning + muscles at night

is 1 muscle just fine ? am i almost under working my muscles, because obv i want improvement rapidly, i feel like its a great long term workout plan to have... can you guys compare yours to it ?? comments and criticisms welcomed but be objective
