I hadn't considered it from this angle. Lifting is a lot of statistical noise without a lot of instant feedback. No wonder so many are obsessed with getting a pump.Exactly. It's also why so many trainers will do introductory workouts for clients with the aim of getting them sore so they FEEL like they did something. It doesn't always sell well to have someone start easy and then tell them "You'll notice results after 3 months."
