I'll reply to you queries in a moment, but In case your wondering what happened to your message, I believed the person you replied to was a spammer, so their message got deleted. So I slightly edited about 3-4 words and the title in your message, to avoid any confusion to other readers.
Hopefully you'll understand
As for your queries, one basic way to get started is to go light and aim for 3 days a week every other day.
This is an example of how you might do things.
Squats, 2 sets, 8-10 reps
Lunges, 2 sets, 8-10 reps
Deadlifts, 2 sets, 8-10 reps
Bench Press, 2 sets, 8-10 reps
Bent over Rows, 2 sets, 8-10 reps
Shrugs, 2 sets, 8-10 reps
Planks 30 seconds
In general with the weights used, small muscle groups, smallest dumbell used, next highest for big muscles.
For machines 1 plate for small muscles, 2 for bigger ones.
This methodology would be sustained for 4-6 weeks to get your body used to the biomechanics of weightlifting.
You could also do some low level cardio like level 1-2 Interval training, which would be non-adaptive hopefully, as it's not like steady state so it's a monotonous form of cardio, so the body shouldn't adapt to it, reducing the efficacy.
Your weekly workout schedule could look something like this.
Day 1. Weights
Day 2. Cardio
Day 3. Weights
Day 4. Day off
Day 5. Cardio
Day 6. Weights
Day 7. Day off
This means not training more than 3 days straight and not having 2 days off back to back, that might slightly eat into progress.
Someone in a Gym could advise further on such matters though, beause of any possily issues regarding your posture, existing muscle imbalances, pre-exisiting levels of strength etc.
Hopefully that answers your question well enough.
