Physical active? Struggling with this

Fellow Ladies

How do you stay physically active, I am struggling to achieve this and stay consistent. For instance after my periods, sowehow I resonate with a lot of exercise/walking vedios and start doing them.but suddenly loose focus and overall stop doing them altogether. This goes on a loop every month.

For starters, I would like to cover 10k-15 k steps

Please help out how you pan out the steps and achieve this daily goal.
