Last workout of the week #5 completed in week 6! Wow what a journey to go through with some amazing women! Highest calorie burn thanks for the fan-freaking-tastic workout again tonight! Killer! Thanks Jessica for the support! I stepped on the scale after burning the most calories of all of the last 25+ workouts that Iʼve done and have dropped >12lbs on the scale at the gym! I had a moment of being proud of all of the work that weʼve done! Canʼt wait for the next journey with the ladies and James!! Cheers!

I can definitely feel changes in my body, like “wow who knew there was bones and muscles there” and just an overall better mood!

Last night I took another Ninja Fitness class and my husband commented on how I am glowing when I come home from these classes. And he’s right! It has been YEARS since I have challenged myself out of my comfort zone, and this challenge and workouts have lived in my subconscious as something really cool to do, but impossible for me. But now, I am doing it. I am scared and skeptical, but I am busting through so many fears, DAILY. It’s not always pretty, but it doesn’t have to be to knock a fear or challenge down. We are evolving from the inside out, and letting our glow shine on. I hope you beautiful ladies are feeling the same!

Benefits Group Fitness Training

Group fitness training has become increasingly popular in recent years, and for good reason. Not only does it provide an opportunity for social interaction and community building, but it also offers a number of benefits for individual fitness. Group fitness classes can be motivating and challenging, pushing participants to work harder than they might on their own. In addition, the group dynamic can create a sense of accountability and commitment, making it more likely that participants will stick to their fitness goals. Finally, group fitness classes are often led by experienced trainers who can provide guidance and support, ensuring that participants are performing exercises safely and effectively. Whether you’re looking to improve your fitness level, meet new people, or simply have fun while working out, group fitness classes can be a great option.
