How do I track Chair exercises for Seniors from tube?

This is going to be a little hard to follow, but bear with me.

MFP (behind the scenes) uses a thing called METS to estimate exercise calories. Loosely, METS is a multiplier that represents average energy (calorie) consumption in a type of exercise based on body weight.

Some examples of exercise nearby to what you're doing are:

* upper body exercise, arm ergometer (2.8 METS)
* video exercise workouts, TV conditioning programs (e.g., yoga, stretching), light effort (2.3 METS)

Conceptually, any exercise with a given METS value burns about the same calories as another exercise with the same METS value.

Hatha yoga has a METS value of 2.5, somewhere in the range of the items above.

MFP has an entry for Hatha yoga in the cardiovascular exercise list: "Stretching, hatha yoga"

I think you'd be reasonably safe logging your exercise under that entry.

Alternatively, when you do your exercise, put the minutes into that entry (without fully logging it). Then, create a personal custom exercise in MFP called "More Life Health for Seniors", put in that same number of minutes, with the calorie value you got from the Hatha yoga entry. Then, next time you use your "More Life Health for Seniors" entry, MFP will do the math behind the scenes to adjust for different numbers of minutes (or changes in your body weight).

That isn't exact, but it should be close enough for the purpose of calorie counting.

Good for you, getting back into an improved self-care routine! That will pay off big time. I'm a senior myself (67) and was a caregiver for my husband before being widowed (long ago, at 43). I'm a big believer in the value of exercise as a quality of life improvement.

Best wishes!
