You smash out a workout on Monday.
Tuesday isn't too bad.
Then Wednesday arrives and suddenly sitting down, climbing stairs or picking something off the floor becomes a whole-body event. 😂
So why can you feel more sore two days after exercise than you did the next morning?
Welcome to DOMS.
What Is DOMS?
DOMS stands for:
Delayed-Onset Muscle Soreness.
It's the soreness and stiffness that can develop after exercise, particularly when your muscles have been challenged in ways they're not accustomed to.
You might notice it after:
- Starting a new workout
- Increasing weights
- Returning after a break
- Running further
- Trying new exercises
- Increasing training intensity
Is It Lactic Acid?
No — and this is a fitness myth worth clearing up.
That next-day or two-day muscle soreness isn't caused by lactic acid remaining trapped in your muscles.
So you don't need a product that promises to “flush out lactic acid” the following day.
Instead, think about supporting your overall recovery.
What Can You Do When You're Sore?
A sensible recovery routine might include:
- Gentle movement
- Adequate hydration
- Good nutrition
- Sleep
- Appropriate rest
- Gradually progressing your training
And remember: being extremely sore isn't necessarily evidence that you had a better workout.
Where Do TENS and EMS Fit?
They're actually two different technologies.
TENS is primarily used for pain management.
EMS electrically stimulates muscles and creates muscle contractions.
Electrical muscle stimulation is sometimes incorporated into training and recovery routines, but current research doesn't support promising that it will prevent DOMS or dramatically speed muscle recovery. PubMed
And I actually think that's a better message for Comfee.
We're not promising a miracle.
We're giving active people another versatile tool they can incorporate into their routine.
Why the Comfee Power3?
The Comfee Power3 gives you both technologies in one portable device:
TENS + EMS.
So whether you're looking for TENS-based pain support or want electrical muscle stimulation as part of your fitness routine, you've got both options available in the same device.
With four pads, it's also well suited to larger muscle areas commonly worked during exercise.
Do You Need to Be an Athlete?
Definitely not.
Recovery matters whether you're:
- Training at the gym
- Running
- Playing sport
- Working a physical job
- Starting a new fitness routine
You don't need to be an elite athlete to look after your muscles.
Gentle Takeaway
That day-two soreness can be a very normal response to challenging your muscles.
Instead of chasing shortcuts, focus on the basics:
Train. Recover. Adapt. Repeat.
And if you'd like both TENS and EMS available in your recovery toolkit, that's exactly where the Comfee Power3 comes in.
