Personally I find meditating right after exercising early in the morning (around 5:30-6am) helpful for having more awareness. Doing it after exercising ensures that you won't fall asleep again and will be awake. Also the awake posture and sitting position is important and helps you to have more attention.
Hope this helps. Love.
There is a great app called Headspace which helps you you to meditate: talks you through how to focus on breathing and put aside certain thoughts. Keep trying and eventually you'll get used to focusing on your meditation
Good luck 🙂
Exercising at the end of the day will help balance body and mind. I find I exhaust my thoughts while exercising so that there is less to ponder on.
Running/walking works well.
Tips for regaining focus while meditating that have worked for me is (1) do short meditations – about 5 minutes – a few times a day instead of one long session, (2) develop a mantra ("Peace, be still" is mine) to recite while meditating, especially when your mind starts to wander, and (3) be kind to yourself when you you find your focus drifting because we all struggle from time to time.
I hope this helps! Take care and happy meditating 😊
