"Naked" row

Wanted to erg at the weekend but "life" got in the way so although I put the model D in the boot on Friday it stayed there until I got back to work today :o( This morning I woke tired, grumpy and feeling fat and old - no change there then - and just did not have the motivation to get up early to row before work so only a lunchtime session and once down and changed I realised I'd left my "electronics" upstairs - so no ergdata, no headphones, no watch (HR) and no music hence "naked" row. The row itself was OK - just set 40 minutes and cranked 20 stokes per minute while keeping the HR in and around 143 (70% HRR when firing)
