at Body Pump after a 2 week absence that is the problem.
Oh, it is uncomfortable. You feel a bit wussy because your really working to lift what you were doing just fine 2 weeks ago & how slack are you anyway? You've been doing the machines during this time, not just sitting around stuffing your face with pie. you *thought* you were working hard on the machines. You thought you were keeping your strength up, but NO.
Can't even make yourself make the effort to maintain your level, because it *hurts* with the extra weight on the leg press.
You finally get your butt back to class and lift that bar, do those squats, nearly collapse during the lunges and think "I'll be feeling that tomorrow."
Well, think again.
The first day back is NOTHING compared to the SECOND day back.
All those things you thought you would feel tomorrow? Your still feeling them today - 2 days later. Only today you HAVE TO DO IT AGAIN! Use those achy muscles to lift that bar, do those squats and try to remain standing for those lunges.
Oh you'll be feeling THAT tomorrow!
