I was in the gym today for 30 minutes. During that time, a young overweight woman did about 3-4 sets of triceps raises and overhead press with light dumbbells, looking at her phone between sets.

She'll quit soon, swearing that resistance training doesn't work.

Yep. You don’t have to work long to see results, but you do have to work hard. If you’re not lifting enough where at the end you are thinking, I can’t lift this anymore, you’re not doing much good.

Doing 10 minutes of low-rep, high-weight sets to failure is better than an hour of goofing around with low weight where you never feel anything.

Example: I work out a lot, but it’s not like I spend hours a day doing it. When I work out alone, I spend 30-60 minutes a day. Rarely longer than that. And in just a bit more than six months, I’ve gotten twice as strong, my endurance has increased dramatically, and I look and feel a lot better.

But that’s because every workout, I go hard and push myself. Otherwise, why waste the time?
