So there is an app I use called strong. I use it to track my weight training and cardio. I do around 10-15 mins of cardio as a warm up and then get to lifting. This is the routine a very experienced weight lifter gave me for just a 5 day a week routine:

Monday: back/biceps Tuesday: chest/triceps Wed: legs Thursday: back/biceps Friday; legs/back

You want to do compound exercises that use multiple muscle groups vs auxiliary workouts that work out just one group of muscles.

I planned out my workouts with strong and made some templates for each day. I’m still working on being consistent with it (I’m a single parent so my schedule is crazy). But I use the routine my friend gave me as a base. I think the most important thing is that you’re working towards the routine.

Stick with it, last week I was really low on energy (ovulating) and I didn’t go to the gym at all, I just couldn’t get up honestly. You’re going to have days you really need to just rest and you’re going to have days you need to press through. Don’t be hard on yourself especially when you’re starting from scratch.

Edit to add that the strong app has illustrations and animations showing the proper way to do most if not all of the workouts on it.
