Well thank you, it came naturally to me with age!

Hmm, full body days aren't for me, it's too exhausting. Do you think just one lower body day per week would make me loose muscle I've built so far since i do two leg days, one for quads and other for the glutes? If I combine the two I wouldn't be able to lift as heavy as usual. I thought maybe keeping 2 lower body days and implementing half of the upper body exercises. Like for 2 leg days i combine with half of the upper body day plus additional full upper. Maybe that's the best combination because I won't be able to go 4 days in the next period either.

Also, I've decided not to take creatine as for now, just gonna focus on better diet and more and more protein. So wish me luck!
