Abstract
At 72, Oprah Winfrey demonstrates remarkable progress in her fitness journey, advancing from a 10-second plank to holding a weighted plank for over a minute. Her transformation reflects a broader commitment to strength training, flexibility, bone health, and sustainable aging—particularly for women. Alongside her fitness milestones, she openly discusses her use of GLP-1 medications for weight management and coauthors a new book with Dr. Ania M. Jastreboff that reframes obesity as a complex, biologically influenced condition rather than a failure of willpower.

| Oprah Winfrey, 72, Proves That She Can Hold a Plank ‘for Over a Minute, with Weights’ |
From 10 Seconds to 60+ Seconds: A Milestone That Represents More Than Core Strength
Progress in fitness is rarely linear. It is built rep by rep, breath by breath. When Oprah shared a throwback video of herself struggling to hold a 10-second plank, followed by footage of her holding a plank for over a minute—with added weights—it symbolized more than improved core endurance. It illustrated consistency, coaching, adaptation, and a reframed relationship with her body.
For aging adults, particularly women over 60, a weighted plank is not simply an aesthetic milestone. It reflects improvements in muscular endurance, bone loading, neuromuscular coordination, and mental resilience.
“Aging does not mean shrinking,” says exercise physiologist Dr. Carla Mendes. “It means adapting intelligently. Strength training is one of the most powerful tools we have for preserving independence and metabolic health.”
Why the Plank Matters for Women Over 60
The plank is deceptively simple. It requires no equipment. It appears static. Yet physiologically, it demands integrated engagement from:
- Transverse abdominis (deep core stabilizer)
- Rectus abdominis
- Obliques
- Gluteal muscles
- Shoulder stabilizers
- Spinal erectors
Adding weight increases mechanical tension and bone-loading stimulus—two key elements in combating age-related muscle and bone loss.
Bone Health and Resistance Training
Women face accelerated bone density decline after menopause due to decreased estrogen. According to the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), osteoporosis disproportionately affects older women, increasing fracture risk.
Weight-bearing and resistance exercises stimulate osteoblast activity, helping preserve bone mineral density. A weighted plank, though isometric, contributes to axial loading through the spine and shoulders.
For clients in their 60s and 70s, structured strength training can significantly reduce fall risk, improve posture, and enhance functional longevity.
Flexibility, Mobility, and Aging Well
Oprah has emphasized that flexibility is as crucial as strength. Mobility determines how well muscles and joints move through range of motion. Tight hips, stiff thoracic spine, and restricted shoulders often limit safe strength progression.
Incorporating mobility drills alongside planks and weightlifting allows aging individuals to maintain movement quality while minimizing injury risk.
“Strength without mobility is incomplete,” notes physical therapist Dr. Hannah Cole. “The two must evolve together.”
The Broader Conversation: GLP-1 Medications and Obesity Reframed
Oprah has also openly discussed her use of GLP-1 receptor agonist medications for weight management. These medications—such as semaglutide and tirzepatide—have reshaped obesity treatment by targeting appetite regulation pathways.
GLP-1 medications work by:
- Slowing gastric emptying
- Enhancing satiety signaling
- Reducing hunger hormones
- Improving insulin sensitivity
Clinical trials have demonstrated average weight reductions of 10–20% depending on dosage and adherence. According to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), these medications represent a significant advancement in chronic weight management treatment.
However, they are not without trade-offs: gastrointestinal side effects, cost barriers, long-term maintenance considerations, and evolving data on extended use.
Shifting the Narrative: Obesity Is Not a Moral Failure
For decades, public discourse framed obesity as a simple equation of discipline versus indulgence. Oprah’s candid acknowledgment of genetic influence and medical support challenges that outdated narrative.
Research consistently demonstrates that obesity is influenced by:
- Genetic predisposition
- Hormonal regulation
- Gut-brain signaling pathways
- Environmental food availability
- Socioeconomic factors
- Sleep patterns
- Chronic stress
The Centers for Disease Control and Prevention (CDC) reports that over 40% of U.S. adults live with obesity. This prevalence underscores systemic influences beyond individual willpower.
“Blame rarely produces behavior change,” says behavioral psychologist Dr. Michelle Alvarez. “Understanding biology reduces shame—and shame reduction improves adherence.”
Strength Training After 70: What the Science Says
Sarcopenia—the age-related loss of muscle mass—accelerates after age 60. Research shows adults can lose 3–8% of muscle mass per decade without intervention.
Resistance training can:
- Increase lean mass
- Improve insulin sensitivity
- Enhance balance
- Support joint stability
- Improve cognitive health markers
Progressing from a 10-second plank to a weighted one-minute hold reflects neuromuscular adaptation and core endurance gains—key markers of functional aging.
The Psychology of Public Progress
Sharing a difficult starting point publicly requires vulnerability. Oprah’s video highlights an important coaching principle: progress is measurable.
Fitness milestones serve as reinforcement loops. When individuals see tangible evidence of improvement—longer plank times, heavier lifts, improved posture—they strengthen self-efficacy.
Self-efficacy predicts long-term adherence more strongly than initial motivation.
Integrating Strength and GLP-1 Therapy: Complement or Substitute?
One emerging question is whether pharmacotherapy replaces lifestyle intervention. Current evidence suggests the most sustainable outcomes arise from combining medication with resistance training and dietary support.
GLP-1 therapy can reduce appetite, but without adequate protein intake and strength training, rapid weight loss may include muscle mass reduction.
Preserving lean mass is critical for metabolic rate and long-term weight maintenance.
Practical Strategies for Aging Clients
1. Begin with Core Stability
Modified planks (knees down, elevated hands) build foundational endurance.
2. Progress Gradually
Add 5–10 seconds per week before incorporating light weight.
3. Prioritize Protein
Older adults may require 1.2–1.6 grams of protein per kilogram of body weight to preserve muscle mass.
4. Include Balance Training
Single-leg exercises reduce fall risk.
5. Monitor Recovery
Sleep quality and inflammation markers matter more with age.
Reducing Obesity Stigma in Coaching Spaces
Language shapes outcomes. Replace:
- “Lack of discipline” with “biological complexity”
- “Cheating” with “unplanned intake”
- “Failure” with “feedback”
Creating psychologically safe coaching environments improves consistency and trust.
Why This Moment Matters
A 72-year-old woman holding a weighted plank for over a minute challenges cultural expectations about aging. It reinforces that strength is trainable at any stage of life.
It also demonstrates that medical tools and physical training are not mutually exclusive. Modern health optimization may involve both evidence-based medication and disciplined movement.
The Long-Term Implications of GLP-1 Medications
Key questions remain:
- Will long-term maintenance require indefinite use?
- How will cost and access evolve?
- What are the effects on lean mass preservation?
Emerging research suggests discontinuation may lead to partial weight regain, emphasizing the need for sustainable lifestyle integration.
Aging Powerfully: The Takeaway for Fitness Professionals
Oprah’s milestone reinforces four coaching truths:
- Strength progression is possible at any age.
- Medical support can coexist with lifestyle change.
- Reducing shame improves adherence.
- Functional strength predicts independence.
Fitness after 70 is not about aesthetics. It is about autonomy.
Conclusion
From a 10-second plank to a weighted minute-plus hold, Oprah Winfrey’s journey reflects persistence, evidence-based adaptation, and modern understanding of obesity science. By combining resistance training, flexibility work, and GLP-1 therapy, she reframes aging as an active, empowered process.
The message is clear: strength is not reserved for youth. It is built intentionally, supported medically when necessary, and sustained through consistent action.
