This makes me think of something Cathe says in (I think) HIIT 40/20 "Its all about what works, as long as you're working."
For me, my fitness routine has evolved throughout my life. I was an avid runner until a knee problem forced me to quit back in 2007. At that time, I was able to get an elliptical, so my workouts were 45 minutes a day on the elliptical and Jari Love Get Ripped dvd's 3x per week. Then around 2009-2010, I started doing Cathe's dvds and got hooked. I think I've done 3 or 4 full rotations of STS and 2 or 3 full rotations of XTrain. In between those years, I also did Beachbody workouts like Brazil Butt Lift and I probably did 2 or 3 full rotations of Chalean Extreme. Then I got hooked on Turbo Fire and Turbo Jam. I did the full Turbo Fire calendar at least once and then would make my own routines using Turbo Fire and Turbo Jam for cardio and throw in some Cathe circuit dvds. In 2019, I discovered Pure Barre DVD's and got hooked on those. I did Pure Barre workouts 3x per week for about 2 years. Then I went back to Cathe cardio, circuits, weights all mixed up. Near the end of 2021, I got serious about weight training and got on this kick of not wanting to do the same workout twice in a month. I bought a ton of Cathe dvd's and would follow a week long rotation of something she published. I also did a week of ICE several times, a week of Strong & Sweaty several times. I was combing through her monthly rotations and picking a week of something here and there. I was crushing this until June 11 when I did something to my knee doing the low impact sprinters on Cardio Slam. So, after taking a week of, I had to totally revamp my routine. During the pandemic, I bought the entire P.Volve series but had never used it. Well, now I finally had a use for it and I'm about to finish the 21 Day Butt Lift series. I've mixed in Cathe's upper body weight training dvds because for now, I want to keep lifting heavy like I had been doing before the knee problem. This week consists of 3 P.Volve butt lift workouts, two Cathe STS upper body workouts and Saturday, I'm going to do ICE Metabolic Total Body. I haven't really done any cardio since June 11, except for doing Fit Split's Low Impact Cardio a few times. What has surprised me is that I seem to have lost 2 pounds since I changed things up. When I bought all the P.Volve equipment, I got a free 90 day streaming membership and I'm still trying to figure out how to stream the workouts from the P.Volve app on my iPhone to my Roku hooked up to a large TV. The P.Volve method is like nothing I've ever done before because the lower body workouts I've done (and so far I've only done their lower body stuff because I didn't want to do lunges and squats with heavy weights until I'd given my knee a month of rest) is all about functional movement. It reminds me of barre and pilates, but with different movement patterns. A lot of it is rooted in physical therapy. If I can get the streaming thing to work, I just might activate my free trial of P.Volve and venture further into those workouts because the equipment is interesting - a slant board, the p.band, which is basically a pair of fingerless gloves attached together with a resistance tube, the p.3 trainer which is similar but has a velcro band that attaches to the ankle and you can attach a resistance tube with a handle or a resistance tube with a small ball to hold onto. Some workouts use light handweights, light and heavy ankle weights, light and heavy ankle bands and the p.ball, which is a small ball attached to a wide elastic fabric strap, similar to Cathe's Boss loop, which you put around your legs at the top of your inner thighs and do various squeezes. Its supposed to activate more butt muscles. So that's my fitness journey in a nutshell. I also think changing things up is key.
