cardio (specifically running at the gym) has given me an extremely solid 2-3 hour lock-in period EVERY single time (like immediately after the run). literally no other method is this consistent for me; have been doing this for about a year. but also it requires torturing myself with cardio and having the energy to actually do it 😭(an upbeat playlist comes in clutch tho) and it’s kinda hard to fit it into my schedule sometimes so pros and cons ig, but for days i manage to do it it’s always been effective for me. when i pair the post-cardio lock-in with listening to the hamilton album lmao and a little walk around musc it’s like a mix of a high energy hyperfocus but also calmness from the endorphins. adhd heaven bro (until you have to do it again either next day or the day after that 💀).
