no such thing as a stupid question. Well obviously there is, that’s just a bullshit thing people say, but your question definitely wasn’t.
I’m not really a fan of that particular routine. It seems to be a full body but yet neglects pretty much all the muscles you can’t see in the mirror.
If the full body workout is a route you want to go down, then something like:
Squats
Dumbell Bench superset with Dumbbell Row
Leg Press
Pulldowns superset with Lateral Raises
Core Stuff
That’s hitting pretty much everything, and takes out what I consider to be exercises that are only used in specific situations (like shrugs - I don’t feel you need to be doing those at this stage). And there’s a little core stuff at the end because I know how much you chicks love that shit.
Supersetting will keep your heart rate up a bit, so more metabolic benefit, and all the exercises are fairly easy to do so you shouldn’t be scared to do the routine by yourself.
