Good for you! I've come to the same conclusions. Consistency is key. Just show up and keep going even though you may not have the motivation. Keep. Everyday.

I have planned to workout at least 20 minutes a day. I won't become Arnold, but at least I'll stay in shape. I used to train more and be consistent, but now it's become somehow harder. But I think with having the habit, it becomes easier to increase (if needed!) over time. But consistency is key.

Cheers to you!
