yesterday i could do all my requirements. My sit up reps have improved, still struggling with push up reps. I have started including a couple of different types of sit ups like v-sit ups (I do not know the names of others). I can feel my abs getting worked. I am still struggling with push ups. I take a step forward and take at least half a step back. I see some progress but still a long way to go. Have a great day all.
