For 5 years I ran the same program.
Upper lower split. Four sessions a week. Two leg days. Average 8 exercises per session.
One compound movement and then 7 isolation exercises to make sure I hit everything twice. I wanted to be sore.
Soreness meant I worked hard. That was the logic.
It worked. I made real progress and I was proud of what I built.
Then I added running.
And suddenly four sessions a week plus running was too much. Recovery was bad. Legs always felt heavy.
I was doing more than my body could handle and I knew something had to change.
So I made a decision that felt wrong at the time.
I dropped a session.
Four days became three. Two leg days became one.
Eight exercises became five targeting multiple muscle groups, all free weights, all focused on moving heavy weight not chasing soreness.
Except for arms those I trained still with isolation but at the end of my training.
Average session went from close to 2 hours down to under 1 hour.
I expected it to feel like losing.
It felt like the opposite.
With 2 hours in the gym I often left feeling like I hadn't finished.
Under 1 hour completely focused I left nothing on the table.
Every set had a purpose. Every exercise earned its place.
The quality went up when the volume came down.
My gym sessions didn't suffer when I added running. They got better when I made space for it.
This taught me something every serious lifter needs to hear:
The goal of being in the gym isn't to get sore. It's to move more weight.
How to make space in your week right now:
Drop one leg day if you're running two or more times a week.
Running already gives your legs serious volume. One strong leg day is enough.
Replace isolation exercises with movements that hit multiple muscle groups.
Barbells and dumbbells over machines. Compound movements over cables and isolation work. You want exercises that build real strength across your whole body not exercises that make one muscle feel pumped.
Focus on lower reps and heavier weights.
Your job in the gym is to stay strong while running improves. That means training for strength not fatigue. Lower reps, heavier load, full recovery between sets. Leave the high rep burnout work for people who aren't running.
You're not doing less. You're doing what actually matters.
Your training is adjusted. The next email is about programming your runs and lifts because most lifters get this wrong in a way that means their legs never fully recover.
Talk soon,
Paco
PS: The lifters who keep their strength while running don't do more. They do less, but better.
