What to do?

Look into Starting Strength by Mark Rippetoe. It isn't what it would seem. It's not a "get huge" thing or something that will turn you into a body builder, but research is showing that strength training is really good for you and will keep you fit and functional. I'm going to buy this book pretty soon but I've read and listened to some of his stuff before.

Bodyweight exercises are always good too. There's some good apps out there that will take you through guided bodyweight workouts. I haven't tried them but people seem to like Sworkit Pro and I think it's free. You could look into that.

Do some research too and find what seems interesting to you. Don't be afraid to try it. Bodyweight exercises are good because you can do them at your own home without worrying about getting anxiety about going to the gym.

You could always buy a jump rope or some perfect push ups. Simple things like that can add to your at home workout as well.

 

I had/have same problem. Improper technique is probably possible but the real reason is limited flexibility on your left side. If your muscles are stiffed muscles in your left shoulder and rotator (scapular winging) it always fucks your technique and you use different muscles that you should.
General rules how to fix muscle imbalance
1. Fix the flexibility (there are so many videos on the youtube about any excercise or any gym problem)
2. Use unilateral exercises (exercises where you have separate weight in each hand for example use dumbbells instead of barbell for bench) - so you can train each side properly.
3. Start working on weak side first and as much excercise you can do on your weaker side do also on your stronger side but no more.

 

Vicious masturbation is the number 1 cause for an imbalance in upper body muscularity. So try out the other hand

Seriously though focus on form...look at yourself in a mirror, watch youtube videos but practice making lifts with both sides look identical.
Use smaller weights when doing this. It really helps muscle balance and work the stabalizer muscles when you do this. Get off the fixed machines and use dumbells, barbells, or the cable machines.

There is also less danger to be a little unbalanced from right tonleft side on your body. The big concern is imbalance between opposing muscles groups (hamstring and quads) especially around major joints. So supplement push exercises with pull exercises

 

Yes I missed flexibility in my last post...very important...my biggest improvement to my health was picking up kickboxing which has improved my lower body flexibility much more than yoga or anything else. Feel amazing
