Built strong minimalist (if you add some A+A swings post session it's really not minimalist IMO) or add S&S on off days
To be purchased here: Built Strong Minimalist by Fabio Zonin
Very good option. I have used this and enjoyed the variety. You need 3 intensity zones for three lifts, and you can choose different lifts for each intensity zone. You can use up to 9 different lifts this way (3 Squat, 3 Pull, 3 Push).
Fabio is working on BTS6, too, giving you up to 18 variations (and, if following Built Strong programming, you might even add isolation work like curls here and there). However, some of the lifts would probably best be done with a barbell.
There are some guidelines in one of Pavel's first kettlebell book.
Yes, the Russian Kettlebell Challenge offers some nice guidelines for KB practice. A bit like Easy Strength for KBs.
Enter the Kettlebell Plus
From MILO Magazine (Vol 17, No. 3). You can choose up to 6 different variations for press, squat, pulling ballistic (swings etc.), pushing ballistic (jerks etc.), and pullups.
You can also use the Total Package Weekly template and enjoy some variety within this framework.
If strength and conditioning are equally important to you, this weekly kettlebell training template will serve you well. Includes 3 sample weeks.
