Hi and welcome back to Get Fit Guy. This week I want to take a look at sources. What is the difference between these two headlines? First, 10 easy moves you can do from home to get a J-Lo butt in just five minutes a week. Secondly,

meta-analysis of the efficacy of the loaded hip extension for glute hypertrophy.

I think it's pretty obvious that one sounds way more fun to read, even for me, but also the way they're written and the type of source material they use is important.

I think critical reading is as important as a skill as critical thinking.
