I  am 61 years old and have degenerative disease on my lower back and want to strengthen the muscles there.  Some of the back workouts shown  I can do slowly but extremely limited without experiencing pain.  Which lower back muscle strengthening exercises can you recommend?

Hi Joey, hope you are well. I am loving your programs - I’m doing 6 day intermediate on rinse and repeat just now and feeling stronger each week - thank you! I wanted to ask your advice please - my partner was diagnosed with ectopic heart beats a couple of years ago and although he has been told they are benign they make him feel like his heart might stop and as a consequence he has been dealing with major health anxieties and fear of exercise, even walking short distances. I would love him to get the benefit of your programs - please could you suggest a sample playlist for him to follow to steadily build his confidence in his body again? Best wishes, Sarah 

hello Joey! I am new to the program and my question is... you hear that our bodies adapt to what excercises we do. is there a proper time to do lower body, upper and abs in order?
