Why do I have a mental block with exercise?

[Roblakeswife]

I have everything at my disposal. Weights, running machine, cross trainer, rowing machine. A push bike. Even a 5m by 3m freezing cold pool in our garden currently that you can actually swim in. I'm hugely lucky. I want to exercise. I need to exercise. I'm really unfit. The rest of my family do but I struggle with it. I feel silly, self conscious, embarrassed, useless, like I cant do it. The only thing I like is running but gave up after multiple injuries (shin splints, plantar fasciitis, tendonitis).
How can I get over this mental block? I try to do something. Tried the cross trainer and my arms hurt within seconds so I gave up.

Go small. Like stupidly small. So small that you can't not do it because that would be ridiculous.

I started training again by saying I'd do 5 squats a day with my bar bell. 5 reps is so few that it would be silly not to do it. It takes less than 30 seconds. Of course, when I've done 5, I tend to do another 5. And then sometimes I do another 5 later on in the day.

But all I have commited to do is 5, so the momentum is there on a daily basis.

I've found going micro works for all manner of things I have a block with: exercise, work tasks, household stuff, self care.

About 3 months ago, I started doing 10 squats whilst waiting for my antiperspirant to dry each morning. I'm now doing 30 each morning. I now have noticeable muscle definition in my quads.
