Difference between XTRAIN, Hardcore and STS

[danylacharite]

Hi cathe,

I have a lot of you DVDs and I enjoy them a lot, they are great.

I have the Xtrain, the new serie that just got out and ordered the Hardcore serie. I am wondering about the STS and see if I need it to change activities or the pace.

What is the difference between those series?

Thanks

Dany

xtrain vs sts

Dany,
If you have the xtrain user guide it tells you on pages 3-5 about the differences of xtrain and sts. Xtrain is Undulating Periodization, STS is Linear Periodization. In the guide, it suggests about a study concluding undulating is better for developing strength gains.
I have both, and like the challenges and options of each.
The more the merrier!
