So i had surgery on my stomach yesterday which means i can do only very light cardio and no strength training for three weeks.
Does anyone have any tips on making sure i do not lose muscle mass?
Do not try to keep every inch of gained muscle during your recovery - esp. not by drugs or supplements (each of which is useless when not working out and will just flatten your purse).
Three weeks is not too long. You may loose about 10% of your strength, but you can easily and fast gain it again when back on track - as usual when you try to get back to a level where you have already been (much easier then extending your capabilities).
I'd suggest to take it slow and to be patient. Keep moving just a little every day, e.g. by walks, and then hit it when you are fully back in business. There's nothing worse than a setback within recovery - injuries may be very serious and lengthen the period to some months.
Get well soon - best of luck!
Thanks for the advice! I actually had to undergo this surgery for the second time because i did not give my body enough time to rest after the first time. So i will definetely try to be patient this time :)
