Hey, I'm managing to actually follow a new year's resolution to exercise every day, even if only to get my heart rate up and not be entirely sedentary. Anyway, I'm pretty sure I overdid it yesterday, so I want to get general opinions on what I should be doing as a beginner. I'd love to get really strong eventually, but I'm trying to be realistic. I've been doing random shit on-and-off for a while now, but right now during my current 5 day streak I've been doing doing push-ups and jumping jacks and I'm managing to maintain the streak so far.
I'm still not really good at push-ups and I can't tell if it's just because I have weak arms or if I'm doing them wrong. Yesterday, I did 4 sets of 20 jumping jacks each and then 20 pushups using my knees, because I read those were still okay even if they're not as good as actual push-ups, so you can start out with those. I can't tell if I'm being lied to or not. I'm not too sure about how I'm doing jumping-jacks either. I'm going to do really low-impact stuff for the rest of today so I don't make anything worse regardless.
Can I get some advice about these?
