Basically I'm not unfit at all (I do 12 hr+ long sessions per week focused around rowing) but the programme I have been following has included a lot of weight training and as I put on muscle fairly easily, it has made me quite heavy-bodied, which I don't really like.
As I've got a back injury at the moment rowing is out, so I'm trying to look into something different to keep my fitness up. I would ideally also like to get a bit leaner.
Using a crosstrainer is fine with my back, and I'm also planning to do wattbiking/actual cycling when the weather improves.
If I'm looking at trying to get a bit leaner, am I correct in thinking that I should do long-duration, low-intensity workouts?
At the moment I am trying out 90min (2x45min with 5min break) wattbike per day, or if I am tired of biking, 45min wattbike and 45min crosstrainer. I'm already getting a bit bored!!
So if there any other exercises (gym based or otherwise) anyone can recommend that won't be too jarring on a sore back I would be *so* grateful.
What are the downsides?
