tues, thurs, sun - I'm doing back, shoulders, legs. 6 days a week cardio and 5-6 abs....too much?
Depends on the volume per muscle group and total time per day.
I was talking to some other people and they said they lift 6 days a week but only hit the same body part once a week. That just doesn't seem right to me.
Yes, thats a whole mindset but not necessary...the thing is if these people are going to overload the muscle past the point of diminished returns then they need to let the recovery happen over a longer period.
Some of the most important things are progression (periodization) and proper diet.
Creatine is good. good the 5-6 meals a day in. They will be smaller. Make Better food choices. Save the beer for a cheat day 1-time a week. try to do better than last week every week. Don't worry about perfection. Try to understand what perfection looks like then see what you can do to inch closer to it!
I'm hoping this sh!t works for me.
The right training and diet works for everyone!

(Except for people with certain health issues)
you should see noticeable changes-progress every 3 weeks. If you don't then check in and work to find out why you don't see progress!
Start a new tread in the training section or journal section with your whole routine with all the specifics...plus all cardio, supplements, and your diet meal by meal...PM me and i will check it for you!
First - go read those threads and make a plan!
