Back in 2014, I went through a very stressful divorce and all I could do at the time was Barre3 30 or 40 minute workouts with some Ballet Beautiful thrown in to mix it up. I couldn't face my intense workouts and Barre3 provided me a total body workout with both strength and cardio. Looking back, I felt better about myself. I was calm through the most difficult times. I also felt more confident and had a positive self image.
In 2015, I switched to mostly Pilates and Essentrics. I have been doing these religiously for the last 3 years. While I love them both and enjoy doing them, I have had another stressful year and haven't felt at peace lately. I don't really do cardio so maybe that is why Barre3 helps me mentally. I get my heart rate up and have to focus on some of the intense balancing moves instead of worrying.
I'm realizing that exercise is about mental health as much as physical health. I took advantage of the Barre3 yearly subscription and have done a Barre3 workout the last three days. I already feel better. It could all be in my mind but I'll take it.
I will definitely add in Pilates and Essentrics too. It just feels good to mix it up.
Anyway, both Barre3 and Essentrics are great full body programs that will make you feel good. They both address posture and flexibility. My weight has been stable for the last 5 years so I'm not sure about weight loss although I've read about weight loss with both. I hope whatever you decide helps you manage your stress and makes you feel better.
