Careful with those pullups. It's been a while.
If you can't do pullups, rig a cable pull-down with the weight at 6-8.
20 pushups is NO JOKE. Snake em if you've got to.
Watch yourself in the mirror during the squats. Get low. Keep your chest up.
If it is icy where you are, 400 m run alt is 2 min of cardio.
Daily extras are likely to make you sore.
