Some lift suggestions:
Military dumbells
standard
alternating arms
arnolds (adds a rotation to the to the lift, works balance
bent rows with bar or bells
triceps work with bar or bells
if you can add a dip station, dips (really works upper body)
good mornings for the lower back
lunges with dumbells
sissy squats
dead lifts
straight leg dead lifts
as mentioned, farmers carry
shrugs, bar and bells
don't read glossy mags that tout all kinds of immediate growth...they lie.
to allow the muscles to heal: alternate lifts during the week so you are stessing a muscle group only once, since, as you age, recovery is of prime importance.
For the tennis elbow, google up tennis elbow treatment. The easiest and most effective treatment is a fore arm brace. Wear the brace all day for a couple of weeks, not just during exercise. I have done this a few times and it works.
Good luck.
