Sorry to hear about your dog shredding up your mat.
I'm trying body weight exercises too (e.g., squats, lunges, etc.), but they're kicking my butt. lol. But no pain, no gain...
I did manage to find a 3lb dumbbell set from Target and it's coming to my apartment.
I realized that I can actually do a lot of exercises with what I have. I never realized it until I started talking to people on Reddit. I never thought about taking a 5lb weight and an 8lb weight, and crossing them over each other in an X shape. Then you can grab the weights in the middle to get to 13 lbs... which is good for me because I'm using a fitness app that wants me to do lunges with 12.5 lb weights (so 13 is close enough).
Anyway, i want to do some walks too. I haven't done any yet though. Yucky rain here... Sounds like you had a g great time.
