tuesday bike workout

Yeah...I did it.
It was a close call though...up in plenty of time but I started laundry, did dishes, tidied up, put supper in the slow cooker...looked at the clock...holy!! Better get on that bike! Today was 4 sets of 8 minutes in my steady state heart rate with 4 minutes easy pedalling in between. And boy do I sweat for these, my hair and shirt are soaked when I am done. Tomorrow is a swim day with another one of Coach Justin's workouts. But I saw no planks...thank god.
And I signed up for...............the 100 push-up challenge!! Is this even possible? I think I can do 10 right now. Coach Justin keeps bugging me to do them as they help your arms and shoulders holding yourself up on the bike, and swinging your arms when you run.
I was actually considering trying this one:
"Twenty-One"
Complete the following for time:
• 20 push-ups/1 sit-up
• 19 push-ups/2 sit-ups
• 18 push-ups/3 sit-ups
• 17 push-ups/4 sit-ups
• 16 push-ups/5 sit-ups
• 15 push-ups/6 sit-ups
• 14 push-ups/7 sit-ups
•13 push-ups/8 sit-ups
• 12 push-ups/9 sit-ups
• 11 push-ups/10 sit-ups
• 10 push-ups/11 sit-ups
• 9 push-ups/12 sit-ups
• 8 push-ups/13 sit-ups
• 7 push-ups/14 sit-ups
• 6 push-ups/15 sit-ups

• 4 push-ups/17 sit-ups
