About this trial
This study examines how adults who take a GLP-1 receptor agonist medication (such as semaglutide \[Ozempic, Wegovy, Rybelsus\], liraglutide \[Saxenda, Victoza\], or tirzepatide \[Mounjaro, Zepbound\]) perform resistance (strength) training before and after starting their medication.
GLP-1 medications are being prescribed more and more often to help people manage type 2 diabetes and lose weight. These medications work well, but a known side effect is that people can lose lean (muscle) tissue along with fat. Losing muscle can make it harder to move, do everyday tasks, and stay strong as we age. Resistance training, things like lifting weights, using resistance bands, or doing push-ups and squats, is the most effective way to keep and build muscle. Yet most adults in the United States do not meet the recommended amount of resistance training, and very little is known about the resistance training habits of people who take GLP-1 medications.
The purpose of this research is to systematically collect information from adults using GLP-1 medications so we can better understand: how often they do resistance training before and after starting the medication; what their sessions look like (frequency, duration, intensity, muscle groups); whether their resistance training is linked to how strong they feel and how well they can carry out daily activities; and what makes resistance training easier or harder while on a GLP-1 medication.
Findings will help doctors, dietitians, exercise professionals, and researchers design better guidance and interventions to protect muscle mass, physical function, and quality of life in people using GLP-1 medications.
Who can join: Adults 18 years or older who are currently taking a GLP-1 receptor agonist medication for type 2 diabetes, overweight or obesity, or weight management, and who have been on the medication for at least three months at a stable dose. Participants must be able to read and respond to the survey in English. People who are pregnant or planning bariatric surgery within the next three months are not eligible.
What participants will do: The study is a single, anonymous, online survey. Interested individuals click the survey link, review a short consent page, and indicate their willingness to participate. Eligible participants then answer questions about their background, current health, GLP-1 medication and dose, resistance training habits before and after starting the medication, self-reported strength and function, and things that make resistance training easier or harder. There are no in-person visits, no exercise tests, and no blood draws.
How long it takes: About 10 minutes total, in one online session. There is no follow-up after the survey and no compensation is offered.
Data privacy: The survey is anonymous. No names, email addresses, or IP addresses are collected or linked to responses. The survey runs on Qualtrics, a secure, institution-approved platform hosted on Ohio State University servers.
The research team hopes to enroll up to 200-300 adults across the United States.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Adult aged 18 years or older
Currently taking a GLP-1 receptor agonist medication
On the GLP-1 receptor agonist for at least 3 months
Using the GLP-1 receptor agonist for type 2 diabetes, overweight or obesity, and/or weight management (self-reported)
Disqualifiers
Currently or planning to become pregnant

Unable to read or respond to the survey in English
Trial population
Adults residing in the United States who are current users of GLP-1 receptor agonist medications for type 2 diabetes, overweight or obesity, and/or weight management. Participants are recruited from community and online settings rather than from a single physical site. Sources include: IRB-approved flyers and posters displayed in relevant clinical settings (e.g., endocrinology, primary care) and community locations; social media outreach (posts and advertisements) directed at adults using GLP-1 receptor agonist medications; and clinic-based outreach in which participating clinic staff post handouts in waiting areas or distribute them to potentially interested patients during routine visits. Interested individuals self-refer by accessing an anonymous online Qualtrics survey link. The study team does not pre-screen, identify, or contact patients directly, and does not access medical records or protected health information at any point.

Treatments tested in this trial
Glucagon-Like Peptide-1 Agonist (GLP-1)
DrugAdults currently taking a GLP-1 receptor agonist (GLP-1RA) medication for at least 3 months at a stable dose (e.g., semaglutide, liraglutide, tirzepatide, dulaglutide, or exenatide) complete a single, anonymous, online questionnaire administered via Qualtrics on Ohio State University secure servers. The survey (\~10 minutes) collects self-reported data on demographics, general health, current GLP-1RA medication with starting and current dose, height and weight, resistance training habits in a usual week before and since starting GLP-1RA therapy (assessed with the Muscle-Strengthening Exercise Questionnaire - Long Form; Shakespear-Druery et al., 2022), perceived muscular strength, activities of daily living, fatigue, quality of life, and barriers/facilitators to resistance training. No in-person visits, physical measurements, biospecimen collection, or follow-up contact are performed.

Trial outcomes
Primary outcomes
Change in Resistance Training Status Before Versus Since GLP-1 Receptor Agonist Initiation
Resistance training (RT) status is assessed via the Muscle-Strengthening Exercise Questionnaire - Long Form (MSEQ-Long; Shakespear-Druery et al., 2022), which captures weekly frequency (days/week), session duration (minutes/session), intensity (OMNI-RES 0-10 scale), muscle groups targeted (7 major groups), and type of muscle-strengthening exercise across four modes (weight machines, bodyweight, resistance bands or free weights, holistic). Each participant reports RT during a usual week BEFORE starting their GLP-1 receptor agonist medication and during a usual week SINCE starting the medication. The primary outcome is the proportion of participants meeting ACSM muscle-strengthening guidelines (≥ 2 days per week engaging all major muscle groups) at each recall period, and the within-person change between the two recall periods.
Secondary outcomes
Resistance Training Dosage Patterns Compared to ACSM Guidelines
Distributions of MSEQ-Long weekly frequency, session duration, intensity, muscle groups targeted, and exercise type, compared to ACSM adult muscle-strengthening recommendations, at each recall period.
