The Trial That Tested Exactly This
Most claims about exercise and weight-loss drugs are extrapolation. This one is not: 195 adults completed a low-calorie diet, then spent a full year randomised to supervised exercise, a GLP-1 medication, both together, or placebo.
195 adults completed a low-calorie diet then spent a year randomised to supervised exercise, liraglutide, both, or placebo. Weight change versus placebo was −9.5 kg for the combination, −6.8 kg for liraglutide alone and −4.1 kg for exercise alone. Body-fat percentage fell 3.9 points with the combination — roughly double exercise (1.7) or liraglutide (1.9) on their own.
PubMed PMID: 33951361 ↗Bottom line: The combination did not simply beat placebo — it roughly doubled the improvement in body-fat percentage compared with either intervention alone. Drug and training are not redundant with each other.
Legion Creatine Monohydrate
Creatine is the most studied supplement in strength training, at 3 to 5 g a day with no loading phase needed. It supports the training this page describes; it does not replace it, and nothing does.

Why Training Changes What You Lose
In a caloric deficit the body has to source energy, and lean tissue is on the menu unless there is a reason to keep it. Resistance training is that reason: mechanical loading signals that the tissue is in use.
Joint guidance from four U.S. nutrition and obesity societies names structured resistance training and adequate protein as the two priorities alongside pharmacotherapy — not as optional extras:
A joint advisory from four major U.S. nutrition and obesity societies sets a protein target of 1.2–1.6 g/kg body weight per day (or about 1.5 g/kg of lean body mass) during active weight loss, distributed at roughly 25–30 g per meal, and recommends structured resistance training alongside pharmacotherapy.

Nothing exotic is required, and the specifics matter less than people assume.
- Two to three sessions per week, full body. More is fine if you recover from it; less than two makes progression difficult.
- Compound movements first. A squat or hinge, a press, a pull. These load the most tissue per unit of time and energy, which matters when both are limited.
- Take sets close to effort. Leaving two or three reps in reserve is enough stimulus; grinding to failure on every set mostly buys fatigue.
- Progress something. Load, reps or sets — if nothing has moved in a month, the stimulus has stopped growing.
Our full routine guide lays out a week of this in detail.
Training When Appetite And Energy Are Down
The honest difficulty on GLP-1 therapy is not motivation, it is fuel. Eating less means training on less.
What works: keep sessions short and dense, drop total volume before you drop intensity (a heavy set of five is more protective of muscle than three light sets of fifteen), and treat a session completed at 70% as a success rather than a failed 100%.
What does not work: skipping the session entirely on low days and trying to make it up later in the week. The consistency is the intervention.
Important: If dizziness, unusual breathlessness or chest discomfort appears during training, stop and speak to your clinician. Rapid weight loss changes cardiovascular and electrolyte status, and those symptoms are not something to train through.
Training Without Protein Is Half A Plan
Resistance training creates the signal to retain and build muscle; protein supplies the material. Either one alone underdelivers.
The joint advisory sets 1.2–1.6 g per kg of body weight per day during active weight loss, at roughly 25–30 g per meal — covered in detail in our protein intake guide. The body-composition data behind why this matters is in the muscle-loss guide.
