Strength training can help you maintain muscle while losing weight, alongside eating habits and regular activity that support fat loss. At proof3 Salt River in Scottsdale, we begin with an assessment so your training reflects your starting point and what you want to achieve.
A 2022 review of resistance-based exercise in people with overweight or obesity found that combining resistance training with calorie restriction helped preserve lean mass during weight loss. That supports including strength work in a weight-management plan; it does not establish what any individual will lose or gain.
You might want to lose body fat, feel stronger on the tennis court or get back into clothes you enjoy wearing. Those goals give us a place to start, and the assessment helps us understand how to approach them.
Why look beyond body weight?
Your weight is one piece of information. Body composition looks at estimated fat and muscle, giving us additional context as we plan your training.
We consider those measurements alongside your strength, movement and current routine. Together, they help your coach choose an appropriate starting level and identify what to work on.
Why does strength training matter when you’re losing weight?
When you’re losing weight, maintaining muscle matters. Strength training gives your muscles regular work through movements such as lifting, pushing and pulling. Your coach guides the technique and resistance, adjusting the exercises as you become more capable.
If you're using a prescribed weight-loss medication, tell your coach about relevant exercise guidance from your care team. Your prescribing team guides the medical and nutrition decisions; our role is coached fitness training.
Our 30/30 sessions combine strength and endurance training. You work in a small group, with coaching that accounts for your ability and experience.
Food choices and overall activity also influence weight loss. A training routine works best when it fits into habits you can maintain over time.
How do you build a routine you can keep?
A useful starting plan should fit your week. We’ll talk about your schedule, the activities you enjoy and what has made consistency difficult in the past.
As you train, we use your performance and reassessment results to review how the plan is working. Changes in strength, endurance and estimated body composition can help guide the next steps.
Common questions about strength training and fat loss
Will lifting weights burn fat?
Strength training on its own doesn’t guarantee fat loss; food choices and overall activity also matter. Its role is helping you maintain muscle while you lose weight, which a 2022 review supported when resistance training was combined with calorie restriction.
Should I do cardio or weights for fat loss?
Both have a place. Strength training helps you keep muscle while losing weight, and aerobic activity adds to your overall activity. Our 30/30 sessions include both: 30 minutes of strength and 30 minutes of endurance.
How can I lose fat without losing muscle?
Combine strength training with eating habits and regular activity that support fat loss. Training your muscles regularly helps maintain them, and tracking estimated body composition, not just weight, shows what’s changing.
