The No.1 New Year's resolution is losing weight when it should be improve body composition.
This may seem pedantic but it's an extremely important distinction to make if you want to finally succeed in achieving that dream physique.

When you go by what the scales say alone you start making some terrible choices on ways to get rid off those excess pounds. Slashing calories, demonising certain macronutrients, crash diets, excessive cardio and even most boot camps are what most people turn to since they all seem to work great in getting quick results. For the first few months of employing these choices the bodyweight seems to fly off. But soon enough results start to taper and eventually become non-existent.

Don't just follow advice given to you regarding any parameter of your training without considering your goals first and how if it truly suits your purposes.

Understand what is required of you in order to achieve your goals.

He then questioned me as to why I trained my key lifts in sets of 1-5 reps.
