Expert Group Fitness Instructors Consultants

I am a fitness trainer who specializes in field of fitness and yoga more than 10years, and also help to motivate people for fitness. I writes with empathy and accuracy and has a knack for connecting with readers in an insightful and engaging way. I contributes regularly to FreakToFit.

I'm the founder and head coach of Siwicki Fitness, an online fitness platform delivering live virtual workout classes to women across the United States. Before launching Siwicki Fitness in 2020, I was a top 1% globally ranked group fitness instructor for Equinox, teaching at their flagship locations in DC, Bethesda, and Tyson's Corner. Siwicki Fitness was built around a simple idea. Women don't need another perfect program. They need one that fits around the life they already have. What sets us apart is the live virtual format. Instructors see members on camera, call them by name, and give real-time feedback. Members range from their 20s to their 70s and average 27 sessions in 8 weeks. I also run The Bridal Bootcamp, a wedding fitness program helping brides prepare for their big day with confidence and strength rather than crash dieting. Personal note: I was diagnosed with Type 1 Diabetes at age 5 and have managed my health through fitness ever since, including playing football at Dartmouth College. I'm available to comment on managing chronic conditions through exercise, virtual fitness, women's fitness across life stages, wedding fitness prep, and the realities of online coaching versus in-person training.

I’m Gwenn, a freelance fitness-wellness writer, a level-4 ACE-certified* Personal Trainer (25 years), and a certified yoga instructor and coach in California. Physically active as a teen dancer, hotfooting it to the fitness world was in plain sight. After certifying in personal training and group fitness, coaching in a few health clubs became master training turf for my future. Corporate fitness programs followed, which is where I found coaching elegance in the C-suite terrain. I was in two brilliant worlds of learning and teaching.  I spent off-hours creating health and fitness newsletters. These broadcasts became my perfect 24/7 digital marketing tool, and I sometimes received the best compliment for any writer: “When is the next one?”  In 2008, I opened a yoga-fitness center where I train clients in group and private sessions 4 days a week. Along with that, managing the business demands broader marketing recipes in website maintenance, landing page marketing, and more fitness newsletters, which are all self-executed responsibilities. Running a successful online fitness accessories store for 7 years enabled excellent website design and maintenance skills.   My creative side carries outside my fitness center’s four walls. I write about self-improvement, personal training, exercise, and yoga, where I am at peace (and at play!). Recently published articles/contributions include Fit&Well, AskMen, Eat This Not That, and YogaGrit. I'm ready for more. If your wellness project banks on information with integrity -- and a bit of sparkle -- I might be your gal. Shall we chat? My expertise is: - mind-body - senior yoga - group fitness - yoga instruction - mobility training - strength training - women's fitness - personal training - functional training - post-rehab training - special populations - senior fitness and longevity ________________ Websites are:  https://GwennJones.com https://AuburnYogaStudio.com Sacramento, CA, USA *ACE CPT (American Council on Exercise)

Hi, I'm [Foysal Mahmud], and I'm thrilled you've found your way to The Workout Haven.

Hi! I’m Tamara, a Certified Pilates Instructor and founder of The Pilates Circuit in NYC. With 9+ years of experience, I specialize in results-driven, athletic Pilates to improve posture, core strength, and overall wellness. I built The Pilates Circuit from the ground up, starting as a solo instructor who simply wanted to train people in a smarter, more intentional way. What began as one private room and a vision quickly became a full-scale, high-performing training brand. I didn’t set out to become an entrepreneur, but when I saw how powerful private, progressive Pilates could be, I knew I had something worth building. Every stage of this business required me to think creatively, lead decisively, and protect the standard I believed in. For two years, I couldn’t hire a single instructor who met the bar I had set. That wasn’t a setback. It was a commitment. I knew the only way to create a truly effective training environment was to build a team that shared the same level of precision, care, and expertise. Today, that team is one of the strongest assets of the brand, and I’m proud to say it reflects years of intentional hiring, training, and leadership. Running a business in Manhattan requires resilience, adaptability, and a deep understanding of what people actually need when it comes to their bodies and their health. It also requires the willingness to rethink traditional models. After COVID, it became obvious that the industry was pushing group fitness harder than people truly wanted. Clients weren’t looking for noise or volume. They wanted attention, connection, and intelligent programming. Recognizing that shift guided some of the biggest decisions I made as a founder and positioned The Pilates Circuit as a leader in private Pilates training. Alongside running the business, I still coach a full roster of private clients each week. Staying on the floor keeps my perspective sharp and rooted in reality. It allows me to bridge movement science with practical, real-world application and ensures that everything we do at TPC is shaped by what actually works, not by trends. As a founder and instructor, I care about clarity, precision, and results. I believe people deserve training that aligns with their goals and empowers them to understand their bodies better. My work combines the mindset of a coach with the leadership of an entrepreneur, and I bring both to every conversation, every client, and every contribution I make as an expert.

Movement professional with a trained eye for detail. Curious, getting a little better each day, and focused on delivering a specific, motivational, and educational training plan. A hard worker, natural leader, and true believer in the phrase "knowledge is power."

Spent my entire career in the boutique fitness space. Started where most coaches start personal training, one client at a time. Grew that into group sessions, then larger groups, then full programs. Then into building brands around what I had learned actually works. Today I run two fitness brands across the Coachella Valley, each built for a different stage of life. Strong Republic Personal Training is for adults over 40 who are playing a longer game. Semi-private strength training built around longevity, mobility, body composition, and quality of life for the next 20 to 30 years. Calmer pace. More deliberate programming. Three studios in Palm Desert, La Quinta, and Palm Springs. The members here are golfers, pickleball players, GLP-1 users, retirees who refuse to slow down, and adults who decided their 60s are not going to look like everyone else's. Fit in 42 is for women 35-45 who want results, energy, and a community to do it with. Small group personal training, the signature 42-day transformation program, kickboxing, HIIT, and strength. Family-owned since 2006. Two studios in La Quinta and Palm Springs. The vibe is high-energy and the bond between members runs deep — most stay for years after their first 42 days. Two brands. Two demographics. One belief — the gym you go to should actually be built for the life you are trying to live.
