Conclusion In conclusion, theories of FDI have evolved through the years. Firstly, Vernon's product life cycle theory is stringently applicable to the Unite states in a particular historical period (1960's).

Deadlifts especially work the adductor muscles of the hips. Torso muscles such as the rectus and transverse abdominus â commonly known as abs -- and the outer-torso serratus anterior and obliques get a secondary workout as the lifter keeps them tight and engaged throughout the motion of the exercise.
The hexagonal shape also reduces contact of the barbell with your shins when you lift the bar off the ground during the deadlift. The biomechanics of a hex bar deadlift are slightly different than of a straight barbell deadlift. The same primary muscles are worked during both, but the recruitment of each muscle is a bit different.
