OK, so I’ve taken up rowing. What with the early mornings, getting shouted at by men I hardly know, losing pretty much every single Sunday morning for months, freezing my cojones off in January in London on the filthy stinky Thames, and ripping shreds off of my hands from the blades, it’s still quite fun and I’m getting in much better shape.
So what I am looking for is this - not being content with my current spot in the boat (novice #2 boat, position 3 in an 8) I want to get better and faster and everything. So I was hoping the wise people on the Dope, or at least the most bored, could recommend a workout programme to help me do this? Here’s my current 6-week programme, due to finish next week. Any rowers out there to offer any suggestions?
Technical Jargon-buster: a rowing machine is called an ‘ergo’; a ‘split’ is the time the ergo says it will take to row 500m, and the ‘rate’ is the stroke rate
Circuit warm-up for heavy weights, is 3 sets of 20 reps of each of these:
squat jumps, press-ups, sit-ups, burpees, dorsal raises, press-ups, sit-ups, squat thrusts
Mon & Wed - circuit + squats, leg presses, barbell power cleans, bench press, military press, bench row - 4 sets of 35 reps each, so low weight
Tue - Ergo castle 2x21 min, with rate = 22 for 5 minutes, 24 for 3 min, 26 for 2 min, 28 for 1 min, then reverse at a split of 1:55 or less; 5 min rest between pyramids
Thu - Ergo for 45 min @ rate 22
Fri - run 5-6 mi
Sat / Sun - either circuits + weight, ergo, or outing on the river for 2 hours
Wednesday I tested myself, and have cut 1:10 off my best 5k ergo test time, so I know it’s working, I just need more! Faster! Better! 
Any recommendations? I should note that in addition to rowing races coming up in March, I’ve a couple of triathlons scheduled in the summer and some other cycle races and whatnot that I’d like to do, as well as some 10k runs, so endurance and cardio fitness is a lot more important to me than bulking up.
