Shade Builder. Above Ground Pool Section. I have watched a youtube video from a company on how to properly install an above ground pool. They showed one option which I will use to level the ground, using a board and level to scrape the dirt away.
Overall, practicing 3 times per week is ideal but remember: a little bit of yoga every day is better than a lot of yoga once or twice per week. If all you can do is 15 minutes per day, do that. The best guide you have to what you need is to spend at least 5 minutes per day seated in quiet.
My general recommendation for low intensity cardio is to simply walk more. Get a tracker or use an app on your phone and accumulate 10,000 steps per day, every day. If you can make some extra time 2-3 days per week to go for a long hike, walk, bike ride, etc. for 30 minutes that would be great. I prefer to do this first thing in the morning. The added benefit is that you get exposure to sunlight.
