To think this is a waste of a GP's time?

GP as in doctor, not grandparent

I'd like some perspective please as I'm struggling with this and a bit miffed.

Last week I walked into my gym (have been a full member for some considerable time) with my 12 week old baby (just wanted to pop my head in and had dc with me).
Straight away one of t he instructors came over, which was nice, thought they just wanted to see baby. So we start talking and I said I wanted to check the place out (has had a refit) before coming in the next day to start back with some exercise.
So they ask if it was a normal delivery and I say no, had a caesarean.

They seemed a bit confused about what exercises I could do (I'm not confused about this. Very confident about what's safe and working within my comfort levels) and suggested i speak to my GP. I tell them I've had my 6 week check and my GP is happy for me to start exercising.

At this point there's two of them (starting to feel a bit unwelcome and uncomfortable now) and I'm being asked to get a doctor's letter to say I can exercise.

This seems ridiculous to me. What do they imagine my doctor is going to say? To specify which bloody exercises I can and can't do?
And I'm 3 months postnatal. When do they stop trying to use a GP' time to cover their arses?
I did agree as frankly I felt embarrased and a bit intimidated but now I think it's a waste of my doctor's time (and mine frankly, it's hard enough trying to get the time to exercise with two small dcs and dh has limited time he can help out with them for this)
So aibu? Wwyd?
Help please wise women of mumsnet. I have a wobbly post baby body that needs sorting out.
Thanks

Well I think it's wasteful and intrusive.

I agree with the advice to just waltz in there. Without the baby attached to you, they probably won't recognise you.

I carried on using the gym when I was pregnant. I didn't tell them I was. I read up on what was safe and what wasn't and took care of my own health.

I started exercising 12 weeks after a caesarean. My PT didnt ask for anything from doc. Maybe they're just covering themselves?

And lazy.
I'm a bit cross with them actually.

I asked my gp at 8 week check what I could do at the gym post section. She said everything except sit ups eye and nothing too direct impact on my abs. I explained this to my gym instructor and he worked out a man for me without needing a letter or freaking out. It's going v well and tummy is fine.
If its any help this was at Virgin Active.

Just ask them if they require the same when a customer has a hysterectomy , mastectomy or vasectomy and if so, how do they know?

Some good comments here, thank you.

I feel a bit wound p by it tbh.

It's such a hassle to arrange child are because dh is very busy and they've pissed on my chance to go to the gym. I won't get another chance until next week. If I don't get a doctor's letter there's always the possibility of a confrontation and if I do I feel they'll have pushed me into using the surgery in appropriately just because they don't know what they're talking about.
Fuckwits.

So! Just been to the gym. It was great.
Didn't get a GP letter bu t no one recognised me.
Feeling very good.
