Most of the people who walk into Push Performance already on a GLP-1 medication make the same mistake in their first week. It’s not that they’re not trying. They’re trying hard. It’s that they’re training like a person who’s eating 2,500 calories a day when they’re eating 1,200.
I’m Jonathan Catlett, owner of Push Performance Training in Bixby. We work with a lot of people from Bixby, Broken Arrow, and South Tulsa who started an Ozempic, Wegovy, Zepbound, or Mounjaro prescription and realized a few months in that they needed actual training, not just a membership at the commercial gym down the road. This post is the conversation I have with them on day one.
The mistake: too much, too fast, too often
Here’s what usually happens. Someone starts a GLP-1. They lose ten pounds in the first month and get motivated. They think “I need to get in the gym.” They sign up somewhere, they start going five or six days a week, and they do what they think they’re supposed to do: an hour of cardio, a few machines, maybe a class. By week three they’re exhausted, nauseous, sore in a way that won’t go away, and wondering why they feel worse than before they started.
The problem isn’t that they’re training. The problem is that they’re training the way a well-fed person trains while their body is running on 40-50% fewer calories than it was last year. Recovery capacity has dropped. Protein intake is lower. Appetite for food AND rest is off. Stacking a high-volume workout routine on top of that is like putting bigger tires on a car that’s running out of gas.
Why more isn’t better on a GLP-1
On a normal calorie intake, your body can handle 5-6 workouts a week. It recovers between sessions. It rebuilds muscle. It adapts.
On a GLP-1 with reduced appetite and reduced intake, your recovery window is compressed. You have less raw material coming in to rebuild from. Push too hard and too often, and you get three bad outcomes stacked on top of each other:
More muscle loss, not less. High-volume training with inadequate recovery and low protein tells your body to cannibalize muscle faster, not preserve it.
Chronic fatigue. You’re already dealing with the appetite-suppression side effects. Adding overtraining fatigue on top of that makes people quit the program (or worse, quit the medication).
Injury. Tired bodies with slow recovery get hurt. I’ve seen too many people on GLP-1s come in with a tweaked back or a knee issue because they were doing too much at a gym where nobody was watching their form or their total workload.
What should actually happen in the first 6 weeks
Here’s the framework we use at Push Performance for new clients on a GLP-1:
Sessions per week: 2-3. Not 5. Not 6. Two or three quality resistance training sessions where a coach is watching you lift, picking weights that challenge you without breaking you, and making sure every session earns its keep. Most of our GLP-1 clients start at 2x/week and only move to 3 once their body is handling the load.
Session length: 35-50 minutes. Not an hour-plus. You don’t need to be in the gym longer. You need the time you’re in there to count.
Intensity: moderate, progressive. The weights should challenge you. But you should leave feeling like you could have done another set, not like you need to crawl to the car.
Cardio: walking, mostly. Hitting 8,000-10,000 steps a day is more valuable than 45 minutes on a treadmill. Walking doesn’t tax recovery the way hard cardio does, and it’s sustainable while your body adjusts.
Rest days: real rest. On rest days, actually rest. Sleep is recovery. Protein intake is recovery. Sitting on the couch is recovery. Recovery is not optional on a GLP-1, it’s the thing that determines whether you build muscle or lose it.
The second mistake (while we’re here)
The other thing I see constantly: people on GLP-1s who start strength training but don’t eat enough protein to make it count. You can lift every day of the week, but if you’re not giving your body the raw materials to rebuild muscle, you’re just breaking it down. For people on GLP-1s, protein intake is arguably more important than the training itself.
Why coached training matters on a GLP-1
I’ll be straight with you: this is where the “commercial gym membership” model falls apart for someone on a GLP-1. At a regular gym, nobody is watching whether you’re overtraining. Nobody is adjusting your program when you report low energy that week. Nobody is spotting whether your form is getting sloppy because you’re under-fueled.
At Push Performance we do personal training in Bixby the way it should be done: a coach is on the floor every single session. For someone on a GLP-1, that isn’t a luxury. It’s the difference between building something that lasts and burning out in six weeks.
What the first month actually looks like with us
If you come in to Push Performance on a GLP-1, here’s what working with a personal trainer looks like in your first month:
Session 1 is a conversation. We go over your medication, how long you’ve been on it, your appetite patterns, your energy, what you’re eating, your history. No workout on day one.
Sessions 2-4 are about establishing a baseline. Light to moderate weights, learning the movements, seeing how your body handles resistance training with your current nutrition.
Sessions 5-8 we start progressing. More load, better form, early strength gains. This is where most people start feeling stronger even though the scale is still dropping.
Week 4+ we evaluate. Protein dialed in? Recovery holding up? We adjust from there.
Bottom line
The mistake is treating a GLP-1 like a motivation boost and throwing yourself at the gym. The fix is treating your reduced-calorie reality with respect and programming around it.
If you’re in Bixby, Broken Arrow, or South Tulsa and you’re on a GLP-1, come in for a conversation. We’ve built Push Performance specifically for people who want to lose fat and keep muscle, not just drop weight and hope it works out.
