Why Functional Strength Training Is Making a Comeback — And How I Fuse It Into My Upper/Lower Workout Split

The Functional Fitness Revolution is Here
Functional fitness training is seeing a major revival in 2025. It’s not just about looking good in the mirror — it’s about moving well in life. ACSM’s 2025 fitness trends list ranks functional fitness training among the rising modalities. ACSM+1
In fact, strength training in general is surging as the dominant shift, with gyms expanding free weight and functional zones to meet demand. Lincoln International LLC
People are craving workouts that translate — strength you can use for daily tasks, longevity, and joint health. Functional fitness gives you that bridge between aesthetics and utility.
What Functional Strength Actually Means
Functional strength goes beyond brute force. It’s:
- Movement in multiple planes (not just pushing/pulling)
- Engaging stabilizer muscles
- Emphasis on mobility + control
- Strength that helps you lift, carry, twist, and move without pain
Machine-only training builds size. Functional training builds usable muscle. A recent review even showed functional movements outperform isolated machine training for strength, mobility, and power. Tom's Guide
How I Fold Functional Strength Into My Split
You know my upper/lower split. Here’s how I inject function into it — no gimmicks, just smart tweaks.
My Weekly Structure (Real):
- Upper A (Chest + Biceps)
- Lower A (Quads + Glutes)
- Upper B (Back + Shoulders + Arms)
- Lower B (Hamstrings + Glutes)
- Optional Upper Pump / Catch-up
- Rest / Mobility Day
Functional Add-ins I Use:
- Unilateral lunges / Bulgarian splits (build single-leg strength)
- Carry work (farmer’s walk or suitcase carry)
- Core + anti-rotation drills (paloff presses, bird dogs)
- Mobility flow at the end of the workout (hips, ankles, thoracic)
- Explosive strength work (box jumps, kettlebell swings occasionally)
These integrate into my primary routine — not replacing it.
Why This Approach Beats the “Hype” Programs
| Problem with Hype | Why My Approach Wins |
|---|---|
| Big lifts, no mobility | You get strength and movement quality |
| Isolated machines | Builds stabilizers and real-life strength |
| Gimmick programs | You build longevity + consistency, not burnout |
Plus, functional strength helps injury-proof you. You’ll carry groceries, pick up kids, and move better in life — not just at the gym.
How to Apply This in Your Training Today
- Add 1 functional movement per lower day (carry or unilateral)
- Swap one machine movement for a free-weight version
- Finish a session with 5–10 minutes of mobility flow
- Track your performance: strength + movement quality
Final Word
The strength resurgence is real. But the winners won’t be the ones chasing trends — they’ll be the ones building durability, function, and volume intelligently.
Do the work that pays dividends in life. That’s what functional strength is truly about.
