In 1986, athletics and weight training were very popular with many more adults in their 20s and 30s than now—about the same time aerobic calisthenics/dancing workouts were popular with many more women. We were much leaner and stronger then. I disagree with regards to focus on grip strength, though. That’s where most factory work alone was lacking. The whole body needs exercise, especially for those working in factories and wanting to avoid injuries. [Been there, done that.]

Grip strength is a valid indicator of overall strength. You can't lift anything if you can't hold it. If you are doing the big three, (squats,press and deadlift) your grip will be commensurate with your PRs. Doing curls ain't gonna cut it.

Go to any weightlifting board and check out the articles regarding grip strength. Grip straps may help, but regardless, grip strength is a limiting factor for heavy lifting and thereby a valid measurement.

These modern gyms are not designed for strength training. The isolation machines are praying used for hypertrophic exercise to build muscle mass. While those Hollywood muscles may look good, they aren't going to help you when it comes to building strength.
