**TL;DR:** On GLP-1, lift 2–3 sessions per week (for muscle preservation) and walk 7,000+ steps daily (for general cardio). Add 1–2 zone-2 cardio sessions if you enjoy it. Skip high-intensity cardio in heavy deficit weeks. Cardio supplements lifting; it does not replace it.

Most people, when they decide to "get serious about exercise," think first of cardio. Treadmill, Peloton, running, classes. On a GLP-1, this hierarchy is exactly backwards.

## The priority order on GLP-1

In order of importance for body composition outcomes:

1. **Resistance training** (2–3x/week) — the muscle preservation lever
2. **Daily walking** (7,000+ steps) — the gut, glucose, and cardiovascular base
3. **Sleep** — recovery and cravings management
4. **Optional zone-2 cardio** (1–2x/week) — cardiovascular fitness, for those who enjoy it

Notice what's not on the list: long, intense cardio sessions multiple times per week. They actively work against the goal on a GLP-1.

## Why intense cardio is the wrong fit

Three reasons:

**1. It burns calories you don't need to burn.** The GLP-1 has already cut your intake by 30–50%. Adding a 700-calorie spin class on top deepens the deficit beyond what's productive.

**2. It eats muscle.** Long, hard cardio in a deficit signals your body to break down lean tissue for fuel. The exact opposite of what we want.

**3. It tanks recovery.** GLP-1 patients are already operating with less fuel. Intense cardio + low intake + poor recovery = chronic fatigue and stalled progress.

## What about HIIT?

High-intensity interval training is a popular cardio modality. On a GLP-1:

- **Short HIIT (10–20 min, 2x/week) is fine.** Doesn't tank recovery, has some metabolic benefit.
- **Long HIIT classes (45+ min)** start to bleed into the "too much" category.
- **Cap at 1–2 sessions per week** during weight-loss phase.

If you love HIIT, keep one or two short sessions. Don't make it your primary mode.

## A reasonable weekly split

**Monday:** Lift (35 min) + walk after work (30 min)
**Tuesday:** Walk (45 min total split through day)
**Wednesday:** Lift (35 min) + walk after dinner (15 min)
**Thursday:** Optional zone-2 cardio (30 min easy bike or jog) OR rest
**Friday:** Lift (35 min) + walk
**Saturday:** Long walk or hike (60+ min) OR optional cardio class
**Sunday:** Rest or gentle yoga

Total active time: ~5–6 hours/week. Split: ~3.5 hr on cardio (mostly walking), ~1.5 hr on lifting.

## A reasonable weekly split for a cardio lover

If you genuinely enjoy cardio and would lift only because you should:

**Monday:** Lift (35 min)
**Tuesday:** Cardio you love (45 min)
**Wednesday:** Lift (35 min)
**Thursday:** Cardio you love (45 min)
**Friday:** Lift (35 min)
**Saturday:** Long cardio (60–90 min)
**Sunday:** Rest

The lifting still anchors the week. Cardio fills the gaps. The minimum 3 lifting sessions are non-negotiable.

## Special cases

**You're a runner / cyclist who's been at it for years.** Don't quit the sport. Just keep lifting alongside it. The combination of consistent training history + lifting + GLP-1 is excellent.

**You're training for an event** (marathon, 70.3, etc.). Acknowledge that you're optimizing for two competing goals (weight loss and event performance). The combination is harder. Talk to a coach about race nutrition, fueling, and lifting frequency.

**You have orthopedic issues.** Walking, swimming, cycling, and rowing are easier on joints than running. All count as cardio.

**You hate lifting.** Find the lifting modality you hate least. Kettlebells. Resistance bands. Pilates with weights. CrossFit (carefully). Strength preservation is non-negotiable; the form of strength training is flexible.

## How to tell if you're overdoing cardio

Signs you're cardio-dominant in a counterproductive way:

- Always tired
- Strength numbers going down despite lifting
- Persistent low energy on workout days
- Disproportionate muscle loss in body composition
- Performance plateau or regression in your cardio sport
- Sleep getting worse

The fix: cut cardio volume by 30–50% and prioritize lifting + protein.

## Walking as the cardio glue

For most GLP-1 patients, the right cardio answer is just: walk a lot. Daily. Outdoors when possible. Add formal cardio sessions if you genuinely enjoy them. Skip them if you don't.

Walking:
- Doesn't eat muscle
- Doesn't tank recovery
- Improves cardiovascular fitness over time
- Helps gut motility (constipation, reflux, sulfur burps)
- Improves sleep
- Compounds across years

## Bottom line

On GLP-1, lifting is the priority. Cardio is supportive. Walk daily. Lift 2–3 times per week. Add formal cardio if you enjoy it, in moderate doses. The mistake to avoid: treating GLP-1 as license to crush yourself with cardio. The medication has handled the calorie burn; your job is to keep the muscle.
