If you train once per week and expect that session to meet all of your physical needs, this post is for you.
One of the hardest conversations we have as personal trainers is about expectations. Specifically, the belief that one (or even two) training sessions per week can fully support long-term health, resilience, and physical robustness.
Becoming a healthy, capable human being requires more than a single weekly workout.
The Physical Qualities Required for Long-Term Health and Performance
There are many physical qualities that contribute to long-term health, performance and resilience:
Strength
Power
Muscle mass
Mobility and flexibility
Cardiovascular fitness
Connective tissue and tendon health
Each of these qualities adapts differently. Some require higher training frequency. Some need specific loading patterns. Others depend more on consistency than intensity.
Trying to meaningfully develop, or even maintain, all of them in a single weekly personal training session is simply not realistic.
What Effective Training Looks Like
To put this into perspective, I train most days of the week.
I strength train two to three days per week and perform cardiovascular training two to three days per week, alternating between short, high-intensity anaerobic work and longer, steady aerobic sessions. Mobility is layered into my strength training by moving through large ranges of motion, allowing flexibility and joint health to improve alongside strength.
Even with five training days per week, I still have to make choices.I’m not training every physical quality maximally at all times. Some qualities I’m building, others I’m maintaining, and some intentionally sit in the background depending on current priorities.
Training is a series of concessions.
Effective personal training isn’t about doing everything. Rather, it’s about prioritizing what matters most right now.
Why One Personal Training Session Per Week Has Limits
When a client trains with me us once per week , our role as coaches is to be strategic with limited exposure. We are constantly asking:
What matters most for this client right now?
What will deliver the highest return on investment?
What can we realistically influence with one weekly session?
If a session focuses heavily on strength, that doesn’t mean cardiovascular fitness isn’t important. If we emphasize mobility, that doesn’t mean power development doesn’t matter.
It means we’re prioritizing the quality that will move the needle most for you.
Trying to do everything in one session often results in doing nothing particularly well.
Why Work Outside the Gym Matters
This is why we strongly encourage our personal training clients to do some work outside our sessions.
That doesn’t have to mean spending hours in the gym every day. Often, it looks like:
Walking regularly around your neighborhood or local trails
Doing short, structured cardio sessions
Following a simple supplemental strength or movement plan
These small, consistent inputs compound over time and support the work we do together in the gym.
One workout per week, even a great one, will never be enough to support long-term health, resilience, and robustness.
Health is a lifestyle input, not a once-weekly event.
Our role as personal trainers isn’t to “fix” everything in one hour.
It’s to help you understand:
What matters most for your body
Why we’re prioritizing certain physical qualities
How to support your health outside our time together
At Eastside Athletics, we believe great coaching builds agency, not dependency. The goal isn’t for your progress to rely on one session per week. It’s for you to learn the skills and develop to autonomy to train for a lifetime.
