I would feel sheepish to call it a routine. But in the spirit of figuring things out together (and putting what i'm doing up for critique from those who know more), i've been doing something like this more days than not the last couple weeks:
-50ish situps (started at like 20. i know ppl now consider situps bad bc of strain on back, i'm just used to them but will likely switch these out soon)
-25-30ish pushups (started around like 10-15)
-with the 10lb weights: lift them up straight extended out from my shoulder, hold 20 seconds. couple reps of these (lighter weights probably better tbh)
-some bicep curls
-30-50 squats (i'm still working on my form, sometimes i use the weights to counterbalance and add some resistance, careful w/ yr knees)
-this spiral arm thing in front of my body, like you're doing the funny arm roller dance move but with weights. i do like 10 or 15 of these, feels good though mindful of your wrists too sometime i notice this can stress them, probably should use 8lbs tbh but i don't have them rn)
-then i kind of need to rest a big so i do some downward dogs and cobras and planks like basic sun salutation yoga vibes. i really notice the blood flowing and energy flowing around here.
then depending on how much drive and time i got i'll basically repeat that routine with progressively fewer reps, like maybe 20 situps, 15-20 pushups, etc.
on the third or maybe fourth round i'll barely be able to do 10 pushups at some point and then i usually stretch more and stop.
when i wake up, 10-20 situps and 10-20 pushups gets me locked into the day in a really helpful way. i notice my posture is better all day, sitting or standing, and my core feels always much more activated.
