I’d do some HIIT training stuff, such as 8x500m with 30 seconds rest between. The aim is to make the last rep as fast as the first rep.
Have a look online at technique. If you are so inclined you can log your metres. They are a damn good way to get fit, and are ranked just less than running for burning calories … but without the high impact on the knee. Like cycling, they use the bigger leg muscles so are great for cardio.
On the Concept2 website you can do your own training plans. There’s also PetePlan http://thepeteplan.wordpress.com/the-pete-plan/ among others.
Distance wise, 500m, 1000m, 1500m, 2000m, 5000m, 10km, Half Marathon and Full marathon.
Time wise, 30m and 60m are longer pieces.
I’ve only recently returned my hire machine, as it was costing a chuffing fortune. But have had a great love-hate relationship with my rowing machine, and even had a bash at the Indoor Rowing championships … not that I got any kind of ranking!
I’d set the resistance bar (on the side of the flywheel) to around “5” … you can see those in the gym that jump on there, whack it up to 10, row frantically for 5 minutes and get off there thinking they’ve done a great row.
Standard times are usually measured for 2000m. Below 8 minutes is good, below 7 minutes is excellent, below 6 minutes you should be rowing for Team GB.
Technique wise, try to keep a good rate of say 25 Strokes per minute, and a pace which you can maintain. For example when I first started using it I could only maintain about 2:45/500m … but over time it improved to about 1:45/500m. Try to drive hard with the legs, and not use your back as a lever.
Mostly, stick some music on and enjoy!
