100 one-arm ones is not too bad after a bit of training. Me and my training partner conquered it relatively quickly last summer. Our current programme has plyometric (sp?) press-ups in pyramid sets. So we start at 10, then do 9 etc down to 1, them come back up to 10 again. The last few sets are killers (8,9,10 reps). We're also doing the same thing with one-arm press-up's, but doing them ascending. After doing the plyo's we only got to 6 (starting at 1 and going up a rep at a time), then back down to 1 again. Will hopefully get to 10 in the next few weeks.
Keep up the good work everyone, stick in 🙂
