I hear some fitness organizations boast that they “never have their clients do the same workout twice,” while other reputable organizations promote using periodization training to create adaptation in the body, followed by the shock of change in the next phase. I get confused over which method is better, or if it’s a combination of the two ideas that works best.
Diet is the fastest way to lose weight as you know. But of course increasing your client’s muscle mass is crucial to help increase his/her metabolic rate and change body composition as mentioned above.
I completely understand you’re confused with whether your client should follow a set routine for a certain number of weeks, then change it up to shock the body out of plateauing. Or, should you just constantly do a different workout. It depends on a couple of factors:
1. How well do you know your client’s body? If you don’t know him/her well or they’re not at a high fitness level, then it might be better to let them adapt to a set program for 6 – 10 weeks (depending on how many times they workout), then move up to the next level for the next phase and so on.
2. How advanced are they? Someone who is very fit adapts very quickly and this type of person would benefit from a workout that changes all the time. This prevents plateauing AND boredom.
3. I find HIIT intervals work best in either scenario. My clients run the gamut of fitness levels and most of them enjoy the Tabata method. HIIT training tends to reap the fastest results in the shortest amount of time.
