Sarcopenia is preventable.
The evidence has been
clear for decades.
Jasclair Wellness Institute is a CNCA-incorporated federal non-profit — Corp. No. 1641314-5 — delivering 12-week virtual resistance training cohorts for Canadian adults 55–70. Grant-supported. Coach-led. Informed by McMaster University's muscle and exercise research program.
The challenge
Sarcopenia — age-related loss of skeletal muscle mass, strength, and function — is a primary driver of falls, frailty, and loss of independence. It is preventable. It is undertreated.
Canadian adults over 70 meet diagnostic criteria for sarcopenia — rising to 1 in 2 by age 80.
Of older Canadians are physically inactive, despite resistance training being the highest-leverage intervention.
Canada crossed the "super-aged" threshold — over 20% of the population is now 65 or older.
Our program
12-week virtual cohorts.
Small-group, coach-led resistance training programs delivered entirely online for adults 55–70 across Canada.
Live group sessions
Weekly 60-minute live Zoom sessions with a coach — form guidance, Q&A, resistance training education, and community check-in.
Structured training
3 sessions per week using a structured, periodized resistance protocol — delivered via a donated training platform at no cost to participants.
Peer community
A private cohort community for peer accountability, shared progress, and connection with others working toward the same goals.
Evidence base
Resistance training is the intervention.
Decades of randomized controlled trial evidence — most authoritatively synthesized by Dr. Stuart Phillips' lab at McMaster University, Canada's world-leading centre for protein and muscle aging research — establish progressive resistance training as the highest-leverage primary prevention for sarcopenia.
Our program protocol is aligned with ACSM guidelines for resistance training in older adults: progressive overload, compound movements, coach-supervised, 2–3 sessions per week.

Year 1 impact
Measurable from day one.
Cohort 1 opens Fall 2026. Year 1 target: 4 cohorts × 25 participants = 100 beneficiaries served across Canada.
Outcome measures
- —Pre/post grip strength or 30-sec chair stand
- —Pre/post sit-to-stand repetitions
- —Self-reported confidence and independence scale
- —Adherence: % of prescribed sessions completed
- —Retention: % completing all 12 weeks
- —Net Promoter Score

Partnerships
Built with support.
JWI programs are made possible by in-kind technology support. Our advisory board is forming, led by researchers and clinicians in aging and physical activity.
Calyber Labs
Calyber Labs donates training platform access to JWI program participants at no cost — enabling structured, coach-prescribed resistance training sessions between live cohort meetings.
This is an in-kind product donation. Calyber Labs is a separate for-profit corporation. JWI does not promote Calyber commercial products, and does not share participant data with Calyber's commercial operations.
Partnership details →Forming
We are building an advisory board of researchers, clinicians, and community health leaders with expertise in aging, physical activity, and sarcopenia prevention.
Our program design is informed by the evidence base of McMaster University's muscle and exercise research program — one of the world's leading centres for aging and resistance training science.
