Her life time experience in the fitness industry has taught her that wellness is very basic and that diet, exercise, attitude, family and friends are the keys to living life to its fullest. Opening Kim’s Gym in Salida has been a dream of Kim’s since 2006 after moving back to Colorado.  It will be a gym that people have fun and get fit.

As an older adult, Kim understands the needs of an aging population.

This drive to help people become more active and fit is Kim’s passion.

Becki Rupp

Certified Personal Trainer | Certified Health & Wellness Coach

I’m inspired by the beauty of Chaffee County, my family and friends to help people discover their path to a more active life.

As a certified personal trainer and health coach, I focus on working with people who are transitioning to their next stage of life get more physically fit.

I’ll help you build your stamina and strength so you can make the most out of life – from daily activities, to playing with grandkids, to your dream vacation. Now that you have the time and resources, you just need the energy to do it!

Together we’ll create a personalized plan based on what works best for your lifestyle, what you enjoy doing, and what you want to be able to do. I’ll keep you motivated and accountable, and you’ll feel the difference!

When I’m not working with clients, you might find me mountain biking on S Mountain, maintaining the Little Rainbow Trail, helping with Town Challenge or skiing at Monarch, hiking in the Sawatch range, paddling a duckie with my husband, or volunteering with Salida Sunrise Rotary.

Ellen Mesaros

I’ve been doing yoga for about 20 years and I’ve been teaching alignment-based yoga for about 10 years.  I became certified at the Anusara Inspired level and that continues to inform my teaching.  I love exploring the effect that subtle movement has on the body and I really enjoy helping my students overcome physical issues through improved alignment in every day movement.  I do not believe that we need to become weak and ill as we age so I continually challenge myself to build strength and stamina.  Yoga is the perfect accompaniment to every other aspect of life from endurance sports to sitting at a desk.  It’s always important to build balance and flexibility into all aspects of life.  I like to make my classes accessible to everyone, fun, and just challenging enough!  See you on the mat.

Amanda Davidson

Amanda Davidson is an ACE certified Group Fitness Instructor. Originally from western New York state, she landed in Salida in 2012, after many years spent exploring life in various parts of the country.

Amanda encourages her class participants to make more space in their lives for self care, to help the restore mind, body and spirit. She believes anyone can improve their overall sense of wellbeing by making positive lifestyle changes.

When she’s not in the aerobics room, Amanda can be found getting lost in nature, camping hiking and kayaking.

Stephanie Treat

I’ve been in the fitness industry for 20 years, weather working at the YMCA as a fitness instructor and personal trainer, or self employed as a trainer.  I love working with people that are just starting out and seeing the improvements they achieve through fitness and living a healthy lifestyle. Its about hard work and most of all for me, its about having fun to reach a goal.


I am currently a certified as a Life Coach, Cycle Reebok and I am working on numerous re-certifications.

Steve O’Neill

After working in corporate for 29 years, it wasn’t long before all the travel and stress started having an effect on my physical health.  I was introduced to Pilates in 1990 as a support program for back and instability issues.  Within a short period I was able to return to my physical activity level of running sprint races and long road and mountain bike rides.


I loved the physicality of Pilates and the challenge to improve myself as the stress of the corporate world continued. It also was a mental challenge that allowed my mind to only focus on myself during my Pilates sessions. At the studio where I studied I was asked to be a physical subject for new instructors to work with as it was felt that I would help a beginner instructor learn what can be done with a client and what could potentially hurt the client.  


In 2000 I left the business world, settled in Salida, and opened my own studio after obtaining Master Pilates Trainer level. Started in a small space on the corner of Sackett and F streets doing just Mat Pilates. Over the next 19 years The Pilates Studio evolved into a 4000 sq ft building with many instructors involved with the studio until I retired July 1, 2019. 


My goal is to help clients reach for their full potential through a variety of training methods.  To help those who need physical work to prepare, or recover from surgery, helping clients recover from injuries sustained during their own physical activities, using The Pilates Method of physical therapy.

Tiffany Smith

Tiffany found fitness when she needed it most, when her life took a hard turn in her middle years and left her feeling sad, confused, lost, and directionless. A friend signed her up for a complimentary membership at the gym she owned, and the darkness Tiffany was experiencing slowly – but ever so surely – began to slip away. With her consistent visits to the gym, light started to emerge, and her confusion became replaced with clarity. 

Tiffany knows that starting a new fitness regime is daunting and intimidating and wants her future clients to know shes been there. She knows what it’s like to weigh the decision to start a fitness routine and hire a personal trainer. She wants you to know that you are not alone, and she can relate to the doubt that might be creeping in. She is highly sensitive to this mindset, and she will help you face it head on, just as she did. You will begin to look forward to working out, as well as realizing that exercise can turn a bad day into a great day.  By making your workouts fun, engaging and effective, she will help you build strength…from the inside out! 

Tiffany Smith has been calling Colorado home for 26 years.  While she resides in Villa Grove in the northern San Luis Valley, she considers herself lucky to be a part of Salida’s vibrant community.  With the Sangre de Cristo and Collegiate Peaks mountain ranges as the backdrop of her life, she draws much inspiration from her surroundings.  She is a passionate amateur photographer, novice cyclist, spirited walker/hiker, river enthusiast, and an all-around animal lover.

LaShay Peterson 

NCCPT Certified Personal Trainer | 200hr RYT | Strong First L1 Kettlebell Instructor | Steel Mace Flow L1 Instructor | RockTape Certified Movement Specialist & Fascial Movement Taping 

LaShay has been in Colorado for 17 years and recently moved to Salida to escape the city and enjoy small mountain town life. She is excited to support the community through fitness by teaching movement and self care. Her dedication to her clients is immeasurable; establishing goals and focusing on your needs comes first. She has worked with people of all ages and physical abilities and believes that movement is accessible to anyone who is willing to try.

Like many of us, LaShay had an on/off relationship with fitness until 2014 when she was diagnosed with Multiple Sclerosis. She knew she needed to lose weight and be strong to fight the autoimmune disorder, so she hired a personal trainer to teach her how to navigate around the gym and build strength. Fitness became part of her life in a way that she had never imagined! Over the course of 4 years she continued to learn from her coaches and mentors and lost a total of 80lbs. In 2018, she became a certified personal trainer and has been coaching Yoga, Kettlebells, and Steel Mace Flow classes ever since. Learning and teaching new movement strategies is one of her greatest passions. In addition, she has a BFA in Fine Arts, is an experienced seamstress, and is working on starting a business making handmade clothing. 

Zel Boone

Zel Boone is a life long student of movement and the interconnectedness of mind, body and spirit. It began with gymnastics and dance, initiating her love of movement, the body’s natural way of expressiing ideas, emotions and experiences. 
 
Zel’s yoga journey began when she  moved from the Philippines to Salida, Colorado in the winter of 2009. After finding it very challenging living in a new country so far away from her family, she decided to go to the gym and attend her first yoga class. She instantly fell in love with yoga and it felt so natural, reminding her of her flexibility and grace from youth gymnastics and dance.
 
She and her husband Tony  have two girls, Zy Elysia 9 and Zara Antonette 7. They love to travel and recreate in the outdoors, whether it be hiking, climbing, biking or camping! She faithfully enjoys morning yoga no matter how she feels, and love sharing her passion with others of all ages. She also love and cherish being a full-time mom,  and inspiring her family by example. After a decade of quietly pursuing her passion, she became a certified RYT-200 Yoga Teacher by Yoga Alliance to share her love of yoga. The discipline and dedication, combined with pranayama, have helped her gain confidence and calmness, even in times of chaos. 
 

Just recently she finished 250 hour Vinyasa Yoga Teacher Training Course with Megan Kahn, et al.of  Yoga Olas In Salida to augment  her skills in teaching especially Vinyasa Yoga.  Zel’s goal and passion in teaching yoga is to encourage others to turn inward and strive to feel their best. Zel’s classes are accessible to every practitioner through modification, alignment, breathing and through listening and honoring their bodies. She continues to expand her practice and teachings through additional trainings such as Ashtanga, Mysore and YIN.   She believes education is continuing process.

Mandy Wright

I have been a group fitness instructor for ten years beginning locally as Salida’s first Zumba instructor and more recently in Denver teaching at multiple locations. I teach groups because I feel the energy is contagious, you work harder and in return achieve your goals quicker.


Inspiring others to create healthier lifestyles motivates me and allows me to thrive. As a trainer and instructor I provide direction and motivation that participants can draw from outside of the studio to live their best life. My personal wellness journey creates compassion for all, as we are all connected and our paths to wholeness are intertwined.

Sandy Baur

Sandy is a Colorado native. She grew up in metro Denver skiing, hiking and camping with her family, which has continued through her adult life as well. Being an elementary school teacher left her a few weeks in the summer to get out of the city and into the mountains for a hike or a week or two of camping.

After retiring from education, it was time to move to a place where her heart is happiest, and that place is Salida. There is plenty to do outdoors and her work at the gym provides an opportunity to meet friendly people every day!
