Studies done on middle age and older groups have shown that resistance training and rigorous work is far better beneficial health effects overall compared to cardio/aerobic alone and even mixed training which is important, but besides that, it just feels better when you get stronger and don’t feel so sluggish.
The body weight exercises definitely get easier when you lose weight, specially when you are just trying to start out. Unfortunately I let myself go, but a few months ago I started training again and feel so much better (can now bench 225 and can do 8 chin-ups) but if you can’t do full sets when starting out with body-weight, there are weights you can use that are less than body weight in the interim. Benching the bar and then adding weight, and doing assisted chin ups or kipping.
Also, as they say ‘never skip leg day’. Nothing does more to improve overall strength (and health) than getting those legs back under you.
Amen to that! Today is day #155 of me doing 2 miles a day on a treadmill. I'm also doing 40-50 sitting leg presses 3 times a week and for my upper body, 25 reps 3 times a week using 5-lb dumbells. My balance is so much better. I was planning to go up to 200 days but now I'm thinking of doing 365 days, which would equal 730 miles. Among other reasons, I plan to never crack another rib during a fall.
