Thank you for the encouragement. Truth is, it is usually more than 20 minutes with set up, warm up, and cool down/stretching. Except for D3. So last night, even though it was after 12 midnight, I decided to go for it anyway. Especially since it was when I used to do D3. Gaining a couple pounds and reoccurring pains was also a motivation :)
I did a quick warm up and minimal stretching afterward, and took everything careful. Still did pretty good, considering it has been about a month since my last workout. I started with one pull up, one chin up, a few negatives 3-1, and most assisted 3-1.
I tried to set it up so that I can save some time off future workouts. I hid the chin up bar on the first floor, instead of the second floor, and put the simple fit chart and pencil and other stuff nearby also. I have kids, and they will find it. Hopefully, afterwards, I will too :)
I'll also mention, to give a context on my progress/fitness, that not too long ago it was my birthday. Let's just say I'm approaching 40.
