I must say I disagree with all of you.

training 3 times a week is very good.

at first of all if you wanna lose weight or not I suggest you should jog 6times a week and that would be from monday to saturday.

Jog as much as you can, there are too many different ways for it.

at second why do you want to train every muscle just 1time per week instead the minimum of 2/3.

Chests are big muscles so if you work out hard.

It takes some time to recover.

Starting with doing that 1-2 times a week is ok.

But doing it 3 times per week is better.

You can train your arms 3 to 6times a week if you like.

Those muscles recover faster.

I suggest you train all muscles 3 times per week.

And NEVER EVER SKIP A MUSCLE unless it still hurts because that's a sign that it's regenerating and growing.

It's still a nice schedule but I learn from the pro's.
