- LM NL does recommend mixing only after 6 to 8 weeks, depending participation frequency. To illustrate: LM NZ does mix after 2 to 4 weeks, but people there are doing 2 or even more of the same classes a week.
where is that info from John? Because the official international LM guidelines are 2-4 weeks. From memory I think it was published in Revolution a while back, which is a mag servicing Australia and Asia.
I think it's wrong to compare with LM-WOF in Auckland. Sure they have 2 studios and lots of classes, but they do have other gyms. And also, the Les Mills gym in Auckland once started off as a small studio that only fit 17 people in it. If they've grown to the point they can hold 200 odd people in their GF room then they must be doing something right

- progressions of exercise: we do recommend doing several programs a week.
That's not what progression is, that's just variety of exercises. To explain what progression is, as a PT you might do this with a new client: starting off with the bench press on a machine and "upgrading" the exercise every 4 weeks.
bench press machine -> bench press bar -> bench press dumbells -> single arm bench press - > flies -> etc
This person might also be running, or biking or doing other weights, but that's not the point. It's each exercise that needs to be progressed.
That's just an example with a single move for a newbie. Let's use a body builder instead as an example, they might progress with reps:
12-15 reps -> 6-8 reps -> 1-5 reps
Or you could progress with speed:
3 down, 3 hold, 3 up -> 2/0/2 - > 1/3/1 -> 1/0/1
Or it can progress in a random order:
6-8 reps -> 20 reps -> 1-5 reps
Depends on your training regieme. There's no real right or wrong, just as long as YOU CHANGE IT EVERY 4 weeks.
Take the person who only does Les Mills classes. Even if they do a variety of programs, if they're doing the same release for too long they're body will get used to it.

- it's true that people get bored and numbers are down until the mixing starts. But that's where the instructors comes in. My numbers are usually up in that period. ATM I am educating my collegues about how the keep their numbers up in the so-called boredom-period' using the own personality while presenting and mixing tools.
think how good you could be, and how many members you could get in if you could mix sooner

Imagine how it would feel if, not only do you keep the numbers up, but also you've got people being turned away at the door. Or more.........what potential is there to increase numbers further?
To be honest there is no scientific basis for using the same release for so long. The only people it benefits are the people who don't go every week.........aren't we trying to get those people to come every week and work out regularly? Sometimes it's hard to get motivated, we have to make it easy for people to exercise every week.....then they'll get hooked. By making them bored (good instructor or not), is that really productive towards getting high rentention rates in the gym? Does that get people in a regular routine? Some people will still go, cuz they're already hooked, and they seek out classes like yours. But what about the rest of them?
