GLP Fitness
You’re losing weight on GLP-1.You’re also losing muscle.
And you won’t notice until it’s too late.
GLP Fitness adjusts your training daily based on appetite suppression, recovery, and performance — so strength doesn’t decline while weight does.

GLP-1 doesn’t protect your muscle.
The drug works. But it doesn’t protect what matters. A meaningful share of what you’re losing isn’t fat — and most people don’t notice until it’s already happened.
A trainer-supervised adaptive strength program, delivered by text, built specifically for GLP-1 users.
GLP-1 works. But it doesn’t protect your muscle.
And that changes what “weight loss” actually means.
of weight lost is lean mass.

When people stop the drug, the fat comes back. The muscle doesn’t.
One-year follow-up of STEP 1 participants who discontinued semaglutide: roughly two-thirds of the lost weight returned — disproportionately as fat. Net body composition was worse than before.
STEP 1 Extension — DOM, 2022
Resistance training. Paired with the drug, it’s the only intervention shown to hold weight loss and lean mass at one year.
In a randomized trial, participants who added structured resistance training to their GLP-1 protocol were the only group that maintained both the fat loss and the muscle at 12 months.
Lundgren et al., NEJM 2021 · Jensen et al., EClinicalMedicine 2024
Muscle preservation is no longer optional — it’s guidance. The 2025 joint statement from ACLM, ASN, OMA, and TOS explicitly calls for interventions that “preserve muscle mass.” AACE 2025 and ACSM 2024 both prescribe resistance training 2–3× per week for anyone on these drugs.
The takeaway is simple:Losing weight is common. Keeping strength is not.
Appetite's down today — day 2 curve. Upper, 35 min. 3 working sets, RPE 7.
It already knows what today should be.
No new app. No dashboard. Two minutes by text — one check-in, one plan built around what your body actually did this week.
Your plan adjusts before you think to.
Three loops, one system. Your week rebalances around what your body actually did — not a static template written six weeks ago.
Signals that matter
Injection day, appetite, energy, sleep, what you actually completed — not heart-rate noise.
- Injection timing
- Appetite & protein window
- Energy + recovery
- Completed volume
Today's plan, built today
Heavy lands on best days. Compression on bad days. Missed sessions rebalance — they don't reset.
- Strength-first programming
- Minimum-viable sessions
- Volume scaled to recovery
- Week compression, not restart
Strength as the KPI
The scale is a by-product. The line we draw is strength — because that's what you're trying to keep.
- Top-set trend
- Weekly retention %
- Injection-cycle pattern
- Weekly trainer review
Most programs adjust after you fail.GLP Fitness adjusts before you do.
Some days the body’s at 40%.
The plan already knows.
Heavy moves off today. Volume compresses. Upper-body neural work lands instead. You don’t explain — it’s already done.
Your body isn’t consistent.
Your plan shouldn’t pretend it is.
- Fixed weekly plans
- Ignore medication effects
- Restart when you miss workouts
- Focus on calories or scale weight
- No human supervision
- Adapts daily to your body
- Built for GLP-1 injection cycles
- Compresses weeks instead of restarting
- Strength is the primary signal
- Trainer-supervised, human in the loop
Adapts daily to your bodyA certified trainer is always in the loop.
Not AI guessing alone. Rules and models run the daily loop. A certified trainer reviews your weekly plan, handles anything the system flags, and is always who you talk to when it matters.
The plan already knows.
“This is the first time my training actually adjusted to how I feel during the week. Day 2 used to wreck me — the plan already knows now.”
“I was down 9 pounds and thought it was working. GLP Fitness showed my strength was dropping. That's when I realized what I was actually losing.”
“It feels like it already knows when I'm going to struggle. I'm down 9 pounds and haven't lost a rep on the bar.”
Strength holds.
The scale drops.
The goal isn’t the scale. It’s what’s left when the scale stops moving. Strength retention is the signal we program against — the one that tells you whether you’re keeping what matters.
Illustrative 12-week trajectory — the pattern muscle preservation produces when resistance training is programmed around GLP-1 cycles. Individual results vary.
You’re already spending $300–$1,300 a month to lose weight.
This makes sure you’re not losing muscle with it.

Common questions.
Short answers. More in your onboarding.
What if I'm inconsistent?
That's exactly who this is for. The system adjusts to missed days instead of resetting your plan.
What if I feel too tired to train?
You won't always get a full workout. You'll get the right workout for that day — sometimes a 15-minute priority lift, sometimes recovery.
Do I need a full gym?
No. Plans adapt to your equipment — home setup, hotel room, or commercial gym.
Is this medical advice?
No. GLP Fitness adapts training. Your prescriber owns the medical relationship and dose decisions.
Do you track calories?
No — on purpose. Strength is the primary signal. Protein timing is the only nutrition guidance.
How private is my data?
Your data is yours. We never sell it, never share with advertisers. You can export or delete it any time.
Can I cancel anytime?
Yes. No contracts. 14-day money-back guarantee on your first payment.
Is it HSA/FSA eligible?
Many members qualify via a Letter of Medical Necessity (sarcopenia / metabolic health). We provide the documentation.

Keeping your strength isn’t.
