Fitness for Life
Functional Fitness?
Functional fitness is definitely a fitness industry 'buzzword' that likely came into existence as a way for a particular fitness routine/gym to differentiate its service from competitors. I would define functional fitness as a training regimen that builds fitness qualities specific to the tasks an individual performs. So with this definition, functional fitness is what any and everyone should be focused on. However, since all forms of fitness are, at the very least, building functional qualities, I find the term to be redundant and gimmicky. Functional fitness can be anything.
• Standing for long periods • Sitting in vehicles • Lifting & carrying heavy things • Jogging to retrieve an item for a principal • Sprinting to prevent an undesirable outcome • Explosive movements to stop a threat in a violent encounter

Mistake #1: You're training is not SPECIFIC enough to the goal of gaining muscle
You're not lifting weights at all
You're lifting weights but not enough
You're doing too much cardio and not enough lifting
You're only using the machines at the gym and doing little to no compound work with barbells and dumbbells
You're doing way too many isolation exercises and doing little to no compound work with barbells and dumbbells
You're trying to train for strength and muscle gain at the same time
