Daily steps and health outcomes in adults: a systematic review and dose-response meta-analysis
A comprehensive systematic review and meta-analysis published in The Lancet Public Health examined data from 57 studies across 35 cohorts to clarify the relationship between daily step counts and various health outcomes. Researchers found that 7,000 steps per day is associated with substantial health benefits, challenging the often-cited 10,000-step target. The analysis revealed a nonlinear dose-response relationship for several outcomes, with the greatest risk reductions occurring between 5,000 and 7,000 steps daily. Compared with walking 2,000 steps per day, individuals who achieved 7,000 steps experienced a 47% lower risk of all-cause mortality, a 25% lower risk of cardiovascular disease incidence, a 38% lower risk of dementia, and a 22% lower risk of depressive symptoms. The benefits extended to cancer mortality (37% reduction), type 2 diabetes risk (14% reduction), and fall risk (28% reduction). While evidence certainty was moderate for most outcomes, the findings suggest that 7,000 steps provides clinically meaningful health improvements and represents a more achievable target for many adults (Nguyen et al., 2025).
How Do I Use This? Set realistic daily step goals that align with current evidence. For clients struggling with the traditional 10,000-step recommendation, reframe the target to 7,000 steps as an evidence-based, achievable goal that still delivers substantial health benefits. Use wearable technology or smartphone apps to track daily steps and gradually progress sedentary clients toward this threshold. Consider that most benefits accrue up to 7,000 steps, so focus on helping inactive clients reach this benchmark before pushing higher targets. This guidance is particularly relevant for middle-aged and older adults seeking practical, sustainable physical activity goals.
This systematic review and meta-analysis investigated whether brief, high-intensity physical activity bouts—termed "exercise snacks"—can improve cardiometabolic health in adults. Researchers analyzed 14 studies involving 483 participants who performed short exercise sessions (typically 1-2 minutes, up to 10 minutes) consisting of sprint cycling, stair climbing, or strength-based exercises, performed 3-5 times weekly for 4-12 weeks. The intervention group demonstrated significant improvements in maximal oxygen uptake (VO₂max) with a standardized mean difference of 1.43, and peak power output improved with an effect size of 0.68. Lipid profiles also improved, with significant reductions in total cholesterol and LDL cholesterol. Benefits were most pronounced in physically inactive adults. Subgroup analyses revealed that exercise snacks lasting more than 2 minutes were more effective for improving cardiorespiratory fitness. The study found no significant effects on body weight or body fat percentage, suggesting exercise snacks primarily benefit cardiovascular and metabolic health rather than body composition (Wan et al., 2025).
How Do I Use This? Incorporate brief, high-intensity activity bouts into daily routines for clients who cite time constraints as barriers to exercise. Design protocols featuring 1-2 minute bursts of stair climbing, bodyweight exercises, or cycling performed multiple times throughout the day. This approach is particularly effective for sedentary office workers or individuals with limited gym access. Emphasize that these micro-workouts can improve fitness markers and cholesterol levels without requiring traditional gym sessions. For optimal cardiorespiratory benefits, structure exercise snacks to last slightly longer than 2 minutes when possible. Manage expectations regarding body composition changes, as exercise snacks appear to improve health markers without significant weight or fat loss.

Fitness and exercise effects on brain age: A randomized clinical trial
A 12-month randomized clinical trial examined whether moderate-to-vigorous aerobic exercise could influence brain structure in 130 healthy adults aged 26-58 years. Participants in the exercise group completed two supervised 60-minute sessions weekly plus home-based exercise to achieve 150 minutes of weekly aerobic activity. Brain-predicted age difference (brain-PAD)—a measure comparing an individual's brain structure to normative data—served as the primary outcome. At baseline, higher cardiorespiratory fitness correlated with younger-appearing brains. After the intervention, the exercise group showed a significant reduction in brain-PAD, with brains appearing nearly one year younger relative to chronological age compared with controls. Cardiorespiratory fitness improved significantly in the exercise group. Notably, changes in body composition, blood pressure, and brain-derived neurotrophic factor did not mediate these effects, and the biological mechanisms underlying the brain age reduction remain unclear. This study provides evidence that sustained aerobic exercise may confer neuroprotective benefits during early and middle adulthood (Molina-Hidalgo et al., 2025).
How Do I Use This? Emphasize aerobic exercise as a strategy for brain health, not just cardiovascular fitness, particularly for clients in their 30s through 50s. Design programs that accumulate 150 minutes of moderate-to-vigorous aerobic exercise weekly through a combination of supervised sessions and independent training. Frame this recommendation within a longevity and cognitive health context to motivate clients who may be less interested in traditional fitness outcomes. Since the mechanisms remain unclear, focus on the established prescription: consistent, sustained aerobic training at moderate to vigorous intensities maintained over months. This research extends the rationale for regular aerobic exercise beyond weight management and cardiovascular health to include potential neuroprotective effects that may reduce age-related cognitive decline.
This 12-week randomized controlled trial with 319 inactive young men tested whether a reduced-exertion high-intensity interval training protocol using burpees could improve both physical and mental health outcomes. Participants performed 2×20-second all-out burpee sessions 3-5 times weekly in either supervised or unsupervised real-world settings. Both supervised and unsupervised burpee training groups achieved significant physiological improvements: 6-8% reductions in body mass and 8-13% increases in VO₂max. Mental health outcomes improved dramatically across all exercise groups, with stress reduced by 49-61%, anxiety by 37-86%, depression by 14-48%, resilience increased by 22-27%, and quality of life improved by 14-27%. Supervised burpee training matched traditional cycling-based sprint interval training for cardiorespiratory fitness gains. Interestingly, the unsupervised real-world burpee group showed smaller physiological improvements but 10% greater improvements in affective responses, suggesting enhanced psychological benefits when individuals train independently (Hu et al., 2025).
How Do I Use This? Prescribe brief, equipment-free high-intensity protocols for clients with limited resources, time, or gym access. A simple program of two 20-second all-out burpee efforts performed 3-5 times per week can deliver meaningful improvements in both fitness and mental well-being. This approach is particularly valuable for individuals experiencing elevated stress, anxiety, or depression, as the mental health benefits were substantial and consistent. For clients transitioning to independent training, recognize that home-based, unsupervised burpee protocols may yield slightly smaller fitness gains but potentially greater psychological benefits. Emphasize that significant health improvements can be achieved in under a minute per session, removing common barriers related to time, cost, and equipment availability.
Digital Wellness Programs in the Workplace: Meta-Review
This meta-review synthesized 29 systematic reviews examining the efficacy and acceptability of digital wellness programs (DWPs) in workplace settings across multiple health domains. The analysis revealed small to medium positive effects for mental health interventions, with effect sizes ranging from 0.24 to 0.54 for stress, anxiety, and depression outcomes. Physical activity programs showed small but significant increases in activity levels (effect size 0.22), while weight management programs produced modest reductions in body weight and waist circumference, particularly among high-risk employees. Sleep management programs demonstrated consistent benefits, though the evidence base remains limited. Acceptability measures revealed challenges: average program uptake was only 11%, attrition rates averaged 32%, and dropout rates reached 51%. However, completion rates improved to 68% in programs that were shorter, personalized, employed self-monitoring features, and used secondary engagement strategies like email or SMS reminders. Tailored programs targeting high-risk employees produced larger effect sizes than universal approaches (Amirabdolahian et al., 2025).
How Do I Use This? When recommending or implementing digital wellness initiatives, recognize that effectiveness varies significantly by individual characteristics and program design. Prioritize personalized, user-friendly platforms with self-monitoring capabilities and regular engagement prompts via multiple channels. Set realistic expectations, as uptake and adherence remain challenging despite positive outcomes for program completers. For organizational clients, recommend needs assessments before implementing digital wellness programs to identify high-risk employees who may benefit most. Emphasize that digital interventions work best as part of a comprehensive wellness culture rather than standalone solutions. For individual clients, suggest apps or wearables that align with their specific health goals—mental health support, activity tracking, or sleep management—while acknowledging that sustained engagement requires personal motivation and organizational support.
