Hi Karrine and a late

to the site!
I think it's great all the input these great 3FC'ers have given here!
I am impressed that you do snow removal

I am a little south of you but if you get anywhere near the amount of snow that we do..ugh...

I hope you have help with the snow removal!! And good for you for the gardening also.
I am hoping you can incorporate strength exercises (and that you are cleared for that from your doctor?) You mentioned weights that are too heavy now but that is great that you have them, work your way up to them gradually, I used to use canned food from the pantry before I bought my dumbbells (oh sorry, they are called free weights

)
I am 54 and want to remain active and flexible as long as I can!
for myself, I go to youtube.com and find the videos by the wonderful young couple Daniel and Kelly,
www.fitnessblender.com I love to just choose a workout depending on my mood and modify to my abilities.
good luck!
