I used to feel exactly like you, until I started for health reasons, and found I couldn’t have been more wrong.
Weight training is the most cognitively demanding thing I’ve ever done, not at all mindless or boring. Using proper form and technique is essentially a martial art, and takes tremendous skill and focus, and can advance in skill limitlessly. As a competitive strongman, I’m also always pushing my skills by lifting and carrying new objects that require different skills and techniques. Some “feats of strength” have taken years of training and strategizing to accomplish. Walking on a treadmill is still boring to me and I avoid it. For the gym to be fun and engaging it needs to be both cognitively and physically demanding, yet possible to accomplish.
Great! I recommend finding some sort of community, club, or coach. Heavy lifts are dangerous if you do them wrong, and you also run the risk of developing bad habits. An hour or two 1:1 with a strength coach from a program like Starting Strength is really worth it. https://coaching.startingstrength.com/
