what do you think of my workout schedule?when should i rest?

Hey everyone, I am trying to build muscle so I have been working out regularly doing many different things. I want to work out today but I don't know what I should do because I did do intense squats, deadlifts, lunges, etc. yesterday. I try not to have a strict rest day... I would rather walk at least 5 miles, or bike, or run, or go to yoga. What do you think?

I'm female, 5'6" and 119 pounds. My main goals are upper-body strength, but I am still trying to build my entire body.

this was what I did all week:

Saturday: 2 mile run, pull-ups, push-ups, Abs.

Sunday: 3 mile power walk, 1 hour of stretching

Monday: 1.5 hour yoga class, 2 mile run, Gym (arms and back)

Tuesday: 12 mile bike ride, 1.5 hour yoga class

Wednesday: 3 mile run, 3 mile bike, 2 hour gym session (pull-ups, push-ups, dumbbells, arms and back)

Thursday: main rest day (2 mile walk)

Friday: 3 mile run

Saturday: 3 mile run (abs + legs)

Now technically, i COULD do arms today... but i really ripped them up on wednesday so I wanted to wait until tomorrow. so my question is.. what kind of stuff can I do today, or on days where I'm still sore in my arms or legs?

everything looks good, i would increase one of the 3 mile runs to 5. that way you have a short day, 2 medium days, and a long day. every few weeks adding a mile to your long day. always keeping the 2 mile day the same, and add .5 miles to one 3 mile day every 2 weeks.

Hi, I think this is more better: 3 day work 1 day rest, again and again!

and the mail question, why you want to build the muscle? you must decide yourself. you need power or muscle?
