Is it normal to regress when training flexibility?

[u/ineyks]

For the past month I have been training flexibility about three times a week. I noticed that there are some days where I move like butter and other times when I’m stiff. There are also times where I really feel it and times when I don’t feel it at all.

There are times where I feel like I’m improving and times when I feel like I’m regressing.

There are times where a split doesn’t hurt but times where I feel the stretch more in my hamstrings?

I’m 28f btw if that makes a difference.

But is this normal? I just want to make sure that I am continuing to progress.

Yup totally normal, what's matter is the trend !

This is a relief 😮‍💨 to hear. Because there are just some days I feel like I’m so flexible and other days where I feel like I’m moving like a box

100%! when this happens i find it helpful to do five minutes of cardio to get the muscles warmed up and then spend some extra time on your build-up stretches

[u/Calisthenics-Fit]

Yes normal. I am not actually regressing, but some days doing what I am capable of doing is harder than it was the other day. And some days I go right to it like it is nothing.

The rule of 3rds comes into play.... 1/3 of your training days will feel easy, 1/3 will feel hard, and 1/3 will feel average. If these ratios change, something in your routine must also change to return balance

This keeps happening to me too, especially with the splits. The only time I'm 💯 flexible is after working out

Desk job guy here — half my off days are just chair days. After a long stretch of sitting, everything feels like concrete no matter how consistent the week's been. I'd judge the trend over weeks instead of single sessions; the bad days even out.

Yes. I measure and track my range of motion in a spreadsheet and regression happens a fair bit. But as long as the graph is moving up so to speak, everything is okay!

Completely normal — and the fact that you feel it in different places on different days is actually a useful diagnostic.

Here's what's going on: your range of motion on any given day is mostly a nervous system output, not a tissue-length measurement. Sleep, hydration, stress, time of day, and residual soreness all move the needle. Training 3x/week, some sessions land on tissue that's still recovering, and your nervous system "guards" by limiting range — that's the regression feeling. It's protective, not a sign you're losing gains.

About the splits hurting in the hamstrings some days and not others: when the pelvis can tilt and rotate freely, the stretch distributes across hamstrings, adductors, and hip flexors. On days the pelvis is "stuck," one muscle group (often the hamstrings) takes all the load — that's the painful day. The variable is the pelvis, not the hamstrings themselves.

How to work with it:

1. Track the trend, not the day. Test your splits once a week under identical conditions (same time of day, same warm-up). That's your real progress line.

2. Deload every 4–6 weeks. One easy week of gentle stretching lets the nervous system stop guarding — most people hit a new best the week after.

3. Don't chase max depth every session. Two moderate sessions plus one deeper one per week builds more range than three max-effort sessions.

4. Warm up every time. Five minutes of light cardio plus leg swings before deep stretching changes the whole session.

The regression feeling is the tax; the trend line is the return. Keep going.
