If you've ever searched for a workout that’s both time-efficient and effective—especially over 40—you may have stumbled across the F4X Training System. Designed by Steve and Becky Holman, F4X (short for “Focus 4 Exercise”) is part of their Old School New Body program. It’s tailored for men and women looking to stay lean, strong, and energized without spending hours in the gym or risking injury with high-impact routines.
In this review, we’ll dive deep into the F4X workout, the exercises it includes, how it felt during training, and who it’s best for.
What Is the F4X Training System?
The F4X workout is built around a unique approach: lower weights, higher fatigue, shorter rest periods. Instead of maxing out every set, you’re encouraged to use about 70% of your one-rep max, but push through controlled repetitions with minimal rest—only around 30-40 seconds between sets.
This method allows you to train efficiently while avoiding excessive joint stress, making it ideal for people in their 50s or 60s—but it’s still powerful enough to challenge anyone in their 30s or 40s who wants to look and feel younger.
There are three phases in the full F4X system:
-
F4X Lean – the foundational fat-burning routine
-
F4X Shape – muscle toning and definition
-
F4X Build – added muscle for those who want more size
Most beginners start with the F4X Quick Start Workout Guide, which eases you into the system with simple compound movements like squats, incline presses, and bent-over rows.
How the F4X Workout Felt: My Personal Experience
As someone who’s cycled through everything from high-volume bodybuilding splits to powerlifting routines, I was skeptical at first. But I gave the F4X training a real shot for six weeks—especially after a nagging shoulder issue forced me to back off from heavy lifting.
Here’s what surprised me:
-
The burn from those slow, controlled reps was no joke.
-
My joints felt better, not worse, after each session.
-
I was out of the gym in under 45 minutes, feeling totally spent.
By week 3, I noticed more vascularity, tighter abs, and a leaner look. The system may seem simple, but the fatigue-based progression sneaks up on you—and delivers.
F4X Workout Exercises: The Core Moves
Unlike flashy “muscle confusion” programs, F4X sticks to the main compound lifts that work:
-
Incline Dumbbell Press
-
Bent-Over Rows
-
Squats (or Chair Squats for beginners)
-
Upright Rows
-
Overhead Press
-
Barbell Curls
-
Triceps Pushdowns or Kickbacks
You perform 4 sets of each movement, following the 4X protocol:
Set 1-3: 10 reps with short rest
Set 4: Go to failure
F4X Workout PDF & Resources
The program comes in digital format, and while some have looked for an F4X workout PDF free, the value really lies in the full guide and instructions from the Holmans. There are also visual aids and scheduling templates included.
For those wondering about the “felt F4X” or Felt FX4, a quick note: those refer to bikes, not workouts—a common mix-up in search.
F4X Training System Reviews: What Others Are Saying
Across the board, most F4X training system reviews mention three standout benefits:
-
Accessibility – Anyone can start, even with past injuries or low experience.
-
Time-saving – The workouts are short but intense.
-
Sustainable – You’re not breaking down your body for gains.
People in their 50s and 60s especially love the longevity of this approach. One 63-year-old user noted how they “felt stronger in everyday life,” while another in their 55s shared how it “boosted confidence and energy without burnout.”
Final Thoughts: Who Is F4X For?
If you’re looking for:
-
A smart, low-impact workout that still builds muscle
-
Something doable even in your 50s or 60s
-
A plan that avoids the “no pain, no gain” trap
Then the F4X workout is absolutely worth a shot.
It’s a method I return to regularly—especially when life gets busy or my joints need a break—and it continues to deliver. Whether you're 35 or 65, F4X proves you don't need to go harder to get better. You just need to train smarter.
