Gotcha. Couple things.
1. Biggest mistake I see newbs in the gym make is not leaving their ego at the door.
Assume you don't know/understand as much as you think do and acquire help from a knowledgeable source. Making friends with other newbs is fine but those are not the folks you wanna be asking for form tips or a spot from, asking exercise selection questions, etc.
2. That wraps up into the other issue which can last past the "new to the gym phase" and that's not having a well-designed plan.
If you are weight training consistently for the first time, your gains will never be this good again. Imma repeat that for you and anyone else that didn't catch that the first time.
If you are weight training consistently for the first time, your gains will never be this good again.
You are doing yourself a disservice by not having a plan and wasting this initial phase of your training. The only thing in the world approaching the gains you can make on anabolic steroids is the newb gains period. I'd take advantage. If freestyling is more fun/enjoyable/less stressful/whatever and you're cool with leaving strength and size gains on the table, by all means.
3. As a rookie in the gym, you prolly don't need to be in the gym lifting more than 4 days and are just wasting gas/time/energy past that. You also don't need a bunch of different exercises or variations as a beginner when sticking to the basics will get you right, but feel free to do you. This is your journey, after all.
