You're doing wonderfully Jo! Don't worry about how many you do, worry about how many you do the right way, to keep your back safe. That's the important part. Glad you're feeling well enough to do some, just be very careful, please.
Jo, I don't want you hurting yourself, you can pump those things out when you're not hurt! Just take it easy, and do what you can without causing yourself any pain (other than the burn of doing a good exercise).
