Are you doing row exercises or actual rowing of a boat? (just curious)
I have been sputtering along this week. Every other day I get a full weight routine in and some very light in door cardio (honestly not enough). And on alternate days my pattern has been just getting a few weight exercises I missed (not even to the point where I break a sweat). On those alternate days I sometimes just do sets in between work and other things throughout the day. And I get at least one rest day. I would like to up my cardio a bit and maybe get involved in something at a Gym again
