I am a 44 year old man returning to moderate weight lifting after 15 years off.
From beginning in my late twenties with a cold flexed right arm measurement of 14" at my smallest, I ended with a measurement of 15 + 7/8 " at my biggest. The majority of that gain happened in about a year.
I bought two 40 lb dumbbells for curling and a 45 for triceps last week, and have gone from just under 15" (rt arm again) to 15.25 in 4 workouts.
I guess muscle does have memory, and I like the initial gains, but I'm wondering how long it could take to break the 16" mark, something I came close to all those years ago, but never broke through.
I am 5' 10 + 3/4 " and weigh 187.
Also, given my stats, what might be the best I could hope to achieve in upper arm size? The distance between bicep insertion point and forearm is a little more than an inch.
Thanks in advance for any insights.
