I was enjoying KCM's Slim Sculpt and Strength and Stamina (my "earlier" kettlebell DVDs together with Angie Miller's Kettlebell Bootcamp... which are all not traditional/heavy duty kettlebell DVD and I only had one that fit such a criteria, namely The Kettlebell Way to Your Perfect Body, Vol. 1: A New "Providence"). And then I finally took the plunge with Lauren Brooks' DVDs (having one acquired her Vol 1 and traded it away without trying as the preview seemed intimidating!) Lauren's DVDs are definitely the hit of the year for me! I've since amassed 80% of what she's put out and often use her routines twice a week
Miss-wise, I finally acquired FIRM Cardio and I ended up Joni O'ing not long after the warm-up - the choreography, the stepping, the equipment changes - I just couldn't deal it even though I've used a few other FIRM workouts from various eras in the last year (FIRM Parts Upper Body all the way to a BSS3 AWT title). I re-visited FIRM Strength and rather enjoyed it so was surprised at my reaction to its companion routine
Also, I tried another Paul Katami routine or two and just couldn't make it past the 5-minute mark- something about the torquing, twisting, fast, higher impact movements don't mesh with me, much as he seems like a solid instructor.
