About Training at Defiant

Training designed around you.

Training at Defiant is part of your health plan, not separate from it. Your coach sees your bloodwork, tracks how your body composition is changing, and knows the GLP-1 protocol you’re on if that’s part of the picture. The program gets built from there, not from a template.

Everything starts with a free consultation. That’s where we figure out the right format for you, whether that’s in-clinic, virtual, or some mix of both, and a training cadence that fits the rest of your week. Pricing and package options get sorted out then too.

Built Around You

+ Free initial consultation with a coach
+ Programming written for your goals
+ Body composition tracking with 3D scans
+ Integration with your weight-loss or longevity protocol
+ Direct access to your coach
+ Recovery built in — HBOT, sauna, and IV options on site

01 — In-Clinic

1-on-1 Personal Training

02 — GLP-1 Add-On

GLP-1 / Weight-Loss Training

Who It’s For

Is personal training right for you?

Clients on GLP-1s

Losing weight on semaglutide or tirzepatide and want to keep the muscle.

First-Timers

New to lifting and want a coach who’ll teach you the basics without making you feel out of place.

Returning Lifters

Back after a break, an injury, or a few life detours. We’ll meet you where you are now, not where you were five years ago.

Longevity-Minded

Training for the next 40 years, not the next photo shoot. Strength, mobility, and metabolic health on a sustainable schedule.

Busy Professionals

Limited time, real results expected. Sessions are efficient, written around your week, and built to fit a calendar that already has plenty on it.

Remote Clients

Outside Lisle or on the road often? Virtual coaching gives you a real coach without the commute.

What’s Included

Every Defiant training program includes…

Custom Programming

A training plan written for your goals, your equipment access, and the days you can actually train. Updated as you progress.

Regular Check-Ins

Scheduled touchpoints with your coach so the plan stays calibrated. Weekly for virtual clients, every session for in-clinic.

Progression Tracking

Loads, reps, RPE, and weekly volume tracked so progress is measurable. You see exactly where you’ve been and where you’re heading.

Body Composition Scans

Periodic 3D body composition scans to track fat mass, lean mass, and circumferences. Especially useful during GLP-1 weight loss.

The Defiant Difference

Training that plugs into the rest of your health plan.

Clinical Oversight

Your coach works alongside our medical team. If you’re on a peptide protocol, GLP-1, or HRT, your training plan accounts for it.

Bloodwork-Aware

For clients who’ve done comprehensive bloodwork with us, training adjusts based on what your labs are actually telling us.

3D Body Comp

Styku 3D scans let us watch lean mass and fat mass move independently of the scale. The detail matters, especially mid-cut.

Recovery Modalities

Pair training with hyperbaric oxygen, infrared sauna, or cryotherapy under one roof.

FAQ

Common Questions

Everything you need to know about personal training at Defiant in Lisle, IL.

Yes. Every new training client starts with a free consultation so we can understand your goals, training history, and any medical context. From there we build a program that fits your schedule, your equipment access, and the modality you choose — in-clinic, virtual, or a hybrid.

Research suggests that a meaningful portion of weight lost on GLP-1 medications like semaglutide and tirzepatide can come from lean mass, including muscle. Resistance training paired with adequate protein intake may help protect lean tissue during a calorie deficit, which can support metabolic rate, function, and long-term outcomes after the medication. Our muscle-preservation guide goes deeper.

Virtual training includes a custom program written for your goals and equipment, regular check-ins with your coach, video review of your lifts when requested, and adjustments as you progress. It is a good fit for clients who travel often, work odd hours, or live outside the Lisle area.

For most clients we recommend two to four training sessions per week. The right cadence depends on your goals, recovery capacity, and life schedule. We map this out during your consultation and adjust as life happens.

Yes. Many of our training clients use the Styku 3D body composition scan to track fat mass, lean mass, and circumferences over time. This is especially useful during GLP-1 weight loss, where the scale alone does not tell the full story.

Programs are built around your goals, schedule, and modality, so pricing varies. We walk through full pricing and package options during your free consultation so you can pick what makes sense without guessing.

We are located at 5100 Lincoln Ave, Lisle, IL 60532, serving Naperville, Downers Grove, Wheaton, Bolingbrook, and the greater Chicago western suburbs. Easy access from I-88 and Route 53.
