After a couple of weeks of prolonged sickness, yesterday was my first PT session in quite a while. It was tough. I had to sit out the last exercise as I was light-headed and feeling a bit sick.
And today I ache in those places you can only ache after some fairly serious weights work. My legs hurt going downstairs from the squats and deadlifts. My shoulders hurt right where the muscles go into the neck - only achievable with strength exercise.
And it feels strangely good.
