I'd strongly second resistance training, it doesn't really take that much time either. A simple program like Starting Strength will have you train for not much more than 60 minutes three days a week and you'll make significant strength gains up to 1.5x body weight easily.
Speaking in effective time, it is obviously more than 60 minutes, I would say rather 160 minutes in the beginning and then getter lower with experience and getting used to it. Resistance training is great, but let's not oversell it to others! A beginner not only needs to buy stuff (or commute to/from the gym) and create their plan and schedule it, they also need to account for spending extra time to correct their pos…
I seriously disagree with this. 60 minutes is more than sufficient if you aren't screwing around. I also think it's baffling that people are still recommending Starting Strength when there are far more efficient and productive programs to start off with.
Especially as a beginner, you can get a significant training stimulus without having to waste 2-3 hours of your day. How absurd. Think 80/20. I even think spending that much time would be more detrimental than beneficial in the beginning.
