> Following a random exercise routine can result in injury.

A trainer can check your form and help you execute the exercise safely but how does an exercise routine injure you?

It might not be super clear from the site shared here, but most of these exercises are done with barbells with weights, or dumbbells. It's not hard for a beginner to do these with incorrect form, and then increase the weight over time, until bad form plus weight results in injury.

Citation needed that bad form inherently leads to injury.
