Here I am again, saying what I keep on saying - NO EXCUSES...because one can ALWAYS do something...
We all have ISSUES..If you have medical issues, it is important to discuss your exercise options with your health care provider before starting any kind of exercise (especially a strength training) program. That being said, once you've been given the "go ahead", it is time to DO.
If you need to avoid certain exercises completely, simply ask about other exercises you can do to work the same muscle groups in a different way.
Add variety (every 4-6 weeks) to your routine such as the tempo, the weight, the duration, etc. in order to continue seeing results.
Do not be afraid to try new things just because of your limitations.
Learning to modify, rather than avoid, will ensure that you're always making progress toward your fitness goals.
Instead of uttering, "I can't", think in a more positive light - maybe I am not able to do this exercise, however, I will DO something to keep my body moving and mobile!
