More Than a Workout: Find Coaching, Confidence, and Community



A successful fitness journey takes more than access to exercise equipment. Women need knowledgeable guidance, personal accountability, and a positive environment that makes them feel supported.


Simply Fit provides a personal fitness experience where women receive professional coaching, build confidence, and become part of a community that genuinely wants them to succeed.


Meet Crystal


Crystal Demers is the owner, health coach, and trainer at Simply Fit. For nine years, she has helped hundreds of women improve their health and work toward meaningful transformation goals.


Crystal understands the journey on a personal level. After having two children, she weighed 220 pounds. Through consistency, hard work, and sustainable lifestyle changes, she lost more than 70 pounds.


Her experience showed her that health is about much more than weight or clothing size. It is about developing physical strength, improving mental well-being, and creating a better quality of life.


Today, Crystal uses that experience to help other women recognize their potential.


She is a NASM Certified Personal Trainer with a specialization in Corrective Exercise, an ACE-certified health and nutrition coach, and holds an associate degree in Exercise Science and a bachelor’s degree in Allied Health. Her education and personal experience allow her to provide knowledgeable, compassionate support to women at every stage of their fitness journeys.


A Complete Approach to Wellness


Lasting results rarely come from focusing on only one part of your health. Simply Fit brings four essential components together:


- Strength conditioning

- Cardiovascular interval training

- Supportive nutrition

- Mind conditioning


Each component supports and enhances the others.


Strength conditioning helps women build muscle and feel more capable in their daily lives. Cardiovascular interval training supports endurance and heart health. Nutrition provides the fuel the body needs, while mind conditioning helps develop confidence, consistency, and persistence.


When these elements work together for a prescribed period, they create a complete approach to health and fitness.


Personal Support—Not a Cookie-Cutter Program


Every woman who walks into Simply Fit has a different story.


One member may want to lose weight. Another may want to stay active and healthy during retirement. Someone else may want enough strength to get on the floor and play with her grandchildren—or simply walk up a flight of stairs with greater ease.


Because every goal is personal, Simply Fit does not use a one-size-fits-all approach.


Crystal takes time to understand each woman’s goals, abilities, and progress. Members receive guidance based on their individual needs instead of being left alone to figure out what to do.


Sessions are scheduled by appointment, creating the accountability and consistency that are often missing from a traditional gym membership. Members know when to arrive, what they will be doing, and that a coach will be there to support them.


Simply Fit also offers weekly nutrition counseling and body-composition checks. These regular check-ins help monitor trends, recognize progress, identify challenges, and make thoughtful adjustments when needed.


Consistency Over Perfection


Crystal’s most important advice for women beginning their fitness journeys is to prioritize consistency and persistence over perfection.


No one needs to perform every exercise perfectly or follow a nutrition plan without ever having an off day. Sustainable progress comes from continuing to show up—even when motivation is low or life becomes busy.


Progress also involves much more than a number on the scale. It might mean:


- Feeling stronger and more energetic

- Walking up stairs more comfortably

- Improving balance and mobility

- Sleeping better

- Feeling more confident

- Lifting the corner of a mattress while making the bed

- Getting on and off the floor to play with grandchildren

- Developing habits that support a healthier life


These everyday victories are worth celebrating. They show how fitness can improve a woman’s quality of life, not just change her appearance.


Women Empowering Women


What truly makes Simply Fit special is its community.


Members work hard, but they also laugh, share stories, encourage one another, and celebrate every accomplishment. Women arrive with different backgrounds, abilities, and goals, yet they are connected by a desire to become healthier and stronger.


Every member is welcomed exactly as she is.


Crystal has created an atmosphere that feels warm, positive, and inviting. Simply Fit has become more than a gym—it is a second home for Crystal and many of its members.


The people surrounding someone during her health journey can make an enormous difference. Working with a coach who is personally invested in her success, alongside women who understand and support her, makes it easier to remain motivated and accountable.


Every Success Story Matters


Over the years, Crystal has seen remarkable transformations. She has worked with women who have lost more than 100 pounds, improved important health markers with guidance from their healthcare providers, gained functional strength, and become more confident in their abilities.


However, there is no single favorite success story.


Every accomplishment matters because every goal represents something personal. For one woman, success may be a major physical transformation. For another, it may be completing her first workout, developing a consistent routine, or having the strength and energy to enjoy retirement.


Simply Fit is personally committed to each member’s progress. Every woman is known, supported, and encouraged throughout her journey.


At Simply Fit, a member’s success is the team’s success.


Find Your Strength at Simply Fit


Confidence grows through action.


It develops after each completed workout, every healthy choice, and every moment a woman realizes she is stronger than she thought. With consistent support and a personalized plan, small steps can lead to meaningful changes.


At Simply Fit, members receive guidance from an experienced coach, a plan designed around their needs, and encouragement from a community of like-minded women. They work hard, celebrate progress, share plenty of laughs, and become stronger together.


Simply Fit is more than a place to exercise. It is coaching, accountability, confidence, and community—all working together to help women become stronger in every part of their lives.


Ready to take the first step? Schedule a visit to Simply Fit, meet Crystal, and discover a community of women ready to support and empower you.

As we age, we naturally begin to lose muscle mass. This gradual loss of muscle directly affects metabolism because muscle is metabolically active tissue. The more muscle you have, the more calories your body burns throughout the day — even at rest. When muscle decreases, your metabolism slows, your daily calorie burn d

One of the most common questions we hear is: Should I eat before I work out? The short answer? In most cases — yes . But what you eat, how much you eat, and when you eat it can make a big difference in how you feel and perform during your workout. If your goal is fat loss, strength building, or simply feeling energized instead of drained, understanding pre-workout nutrition is key. Why Eating Before a Workout Matters Your body needs fuel to perform. When you exercise — especially during strength training — your body primarily uses stored carbohydrates (glycogen) for energy. If those stores are too low, you may feel fatigued, lightheaded, weak, or unable to push yourself. Skipping meals before a workout can lead to: Lower energy Reduced strength output Poor recovery Increased muscle breakdown If you’re training hard but under-fueled, you’re not getting the full benefit of your workout. What Should You Eat Before a Workout? The best pre-workout meal or snack includes a combination of protein and carbohydrates. Carbohydrates provide quick energy. Protein helps preserve muscle and supports recovery. A few simple examples include: Greek yogurt with fruit A protein shake and a banana Toast with peanut butter Oatmeal with protein powder mixed in Eggs and a small portion of fruit You don’t need anything complicated or fancy. The goal is balanced fuel that’s easy to digest. How Long Before a Workout Should You Eat? Timing depends on how much you’re eating. If it’s a full meal, aim for about 2–3 hours before your workout. If it’s a small snack, 30–60 minutes beforehand is usually ideal. Everyone’s digestion is a little different, so this may take some experimenting. If you feel sluggish or uncomfortable, adjust timing or portion size. What If You Work Out Early in the Morning? This is common — especially for busy women balancing work and family. If you’re training first thing in the morning and don’t feel hungry, a small, easy-to-digest snack like half a banana, a few bites of yogurt, or a protein shake can be enough. Even a little fuel can improve performance compared to training completely fasted. Some women feel fine working out without eating first, especially for lighter sessions. However, for strength training and higher-intensity workouts, having at least a small amount of fuel usually leads to better results. Does Eating Before a Workout Slow Fat Loss? This is a major myth. Eating before a workout does not prevent fat loss. In fact, being properly fueled can help you train harder, lift heavier, and preserve muscle — all of which support fat loss long term. The key is your total daily nutrition, not whether you eat immediately before exercising. Under-eating consistently can actually slow metabolism, increase cravings, and stall progress. Proper fueling supports sustainable results. The Bottom Line If you want stronger workouts, better energy, improved recovery, and long-term fat loss, eating before your workout is usually a smart choice. You don’t need a large meal. You don’t need supplements. You just need simple, balanced fuel that supports your body. At Simply Fit, we don’t just focus on workouts — we help you understand how to fuel your body for real results. Strength training paired with proper nutrition is what creates lasting change.

Creatine is one of the most researched supplements in the fitness world—yet it’s still surrounded by myths, especially when it comes to women. Many women wonder: Will it make me bulky? Is it safe? Do I even need it? Let’s break down exactly what creatine does for women, the real benefits, potential side effects, and how to use it effectively. What Is Creatine? Creatine is a naturally occurring compound found in your muscles and brain. Your body produces it on its own, and you also get small amounts from foods like red meat and fish. Its primary role is helping your body produce energy—specifically during short bursts of high-intensity activity like strength training, sprinting, or interval workouts. Benefits of Creatine for Women 1. Increased Strength and Performance Creatine helps your muscles regenerate energy faster, which can lead to: Lifting heavier weights Completing more reps Improved performance during high-intensity workouts This doesn’t mean getting bulky—it means getting stronger. 2. Improved Lean Muscle Tone Creatine supports muscle development by allowing you to train harder and recover faster. For women, this typically results in: Better muscle definition A firmer, more toned appearance Improved metabolism due to increased muscle mass 3. Better Workout Recovery Creatine can help reduce muscle soreness and speed up recovery between workouts, making it easier to stay consistent with your training routine. 4. Cognitive and Mood Benefits Emerging research shows creatine may support brain health, focus, and mental fatigue—especially helpful for busy women balancing workouts, work, and family life. 5. Bone and Muscle Health as You Age Strength training is essential for long-term health, and creatine can support muscle and strength maintenance as women age, helping protect mobility and bone health. Common Myths About Creatine and Women “Creatine causes weight gain.” Creatine may cause a small increase in water retention inside the muscles—not fat gain. This often improves muscle fullness and performance, not the number on the scale long-term. “Creatine makes women bulky.” Women do not have the testosterone levels required to become bulky from creatine. Instead, it supports strength and lean muscle tone. “Creatine isn’t safe for women.” Creatine is one of the most studied supplements available and is considered safe for healthy adults when taken as directed. Potential Side Effects Creatine is well-tolerated by most people. Some women may experience: Mild bloating when first starting Digestive discomfort if taken in large doses at once Drinking enough water and sticking to the recommended dose helps minimize these effects. How Should Women Take Creatine? Recommended dose: 3–5 grams per day Timing: Any time of day works—many women take it post-workout or with a meal Loading phase: Not necessary Best type: Creatine Monohydrate (simple, effective, and well-researched) Consistency matters more than timing—daily use delivers the best results. Is Creatine Right for You? If you strength train, want to feel stronger, recover faster, and get more out of your workouts, creatine can be a powerful (and affordable) addition to your routine. As always, check with your healthcare provider if you have any medical conditions or concerns. Creatine isn’t just for bodybuilders—it’s a practical, science-backed supplement that can help women feel stronger, more confident, and more capable in their workouts and daily life. At Simply Fit, we focus on sustainable strength, confidence, and long-term health—not quick fixes or extremes.
