You probably don't need more sets per day. You just need more intensity.
Doubling your training volume doesn't necessarily double your muscle building stimulus, but it could drastically increase your fatigue.
Let me explain...
Something I always say to friends, family, and clients is that there's a nonlinear dose response relationship between training volume and muscle growth.
In other words, more work doesn't always mean an equal return on your investment.
Every additional set increases fatigue, but each additional set generally provides less muscle building stimulus than the one before it.
This is called diminishing returns.
For example, imagine your first set provides 100% of the initial stimulus.
Your second set might give you 66% as much stimulus as the first set...
Your third set, 39%.
Your fourth, 23%.
And your fifth, just 16%.
These are obviously estimated percentages, not universal measurements, but they illustrate the point.
Doing 10 sets doesn't mean you're getting 10 times the stimulus of doing one.
Eventually, you're accumulating considerably more fatigue for progressively smaller returns.
Instead of adding sets, focus on making the sets you're already doing more productive. Train closer to failure. Occasionally incorporate drop sets or rest pause sets. Become more comfortable with being uncomfortable.
This is also why I'm not a big fan of traditional bodybuilding "bro splits," where someone crams an entire week's worth of training for one muscle group into a single workout.
Unless you're an advanced bodybuilder with exceptional recovery capacity, you're usually better off distributing that volume throughout the week.
Instead of doing 20 sets of chest on Monday, try doing six or seven sets on Monday, Wednesday, and Friday.
You'll maintain better performance, manage fatigue more effectively, and give yourself more opportunities to train hard and recover.
Muscle doesn't grow because of how much punishment you can tolerate. It grows because you provide enough stimulus to force an adaptation and enough recovery to allow it.
More sets don't always mean more muscle.
The goal isn't to do as much work as possible. It's to get as much growth as possible from the work you do. Workouts are like alcohol, more isn't always better.
