kettle bells are the way to go for "most" moves but dumbells still have their place - all I can say is don't look at what is going on around you, just look at what YOU are doing and take is slow and patient - I'll be 68 in June, I've been a "gym rat" since age 14, more injuries than I can ever remember OR count and nearly every one of them was caused by ego, impatience or being just plain stupid -"competition" is fun but if you allow it to get out of hand you'll most likely end up regretting what you did (or attempted to do)- 90% of it is just getting to the gym or devoting time to yourself and sticking with it - OH, and NO supplements that require a needle or are expensive, a well balanced diet (NO FADS HERE !), clean protein and COMPLEX carbs and some ANIMAL FATS !! (read the studies)- then don't forget the cardio phase of your workouts - I'm off the soapbox now ….. I've just seen/heard a lot of stupidity in gyms is all …..
