I decided a couple of months ago to try and gain weight, I had lost nearly 3 stone post SCA & OHS 3 years ago.
I have struggled all my life to put weight on, started weight training in my early 20's and slowly went from 9st to 12st, maintained until SCA.
Anyway, set myself a goal to get to 11st (70kg), I started on the 10th May at 10st 4lb (65.3kg), weighed myself on Fri and was 69.5 so less than half a kg to go, was quite pleased.
Been eating around 4,200 calories a day, on weight training days, a bit less on cardio days.
One thing I noticed is my resting HR has gone from 50bpm to 56bpm, I wondered if this was down to the extra weight I was carrying, then thought maybe it was more down to the fact that my heart is working harder even at rest, to process all the extra calories! I had a chat with one of Dr's and they agreed it was probably the extra workload on my body to process the cals, particularly as I tend to eat something every hour.
Well hopefully i'll hit 11st tomorrow, then i'm going to cut back and maintain for a while to give my body a rest, interested to see if RHR goes back down!
