Ah, I had forgotten about this thread.
That's good progress, Scotty! Adding weight & strength will help for sure.
For my son, here's what I had posted previously, updated with a recent outing this past weekend:
- Mar. 2013 (age 12 yrs, 2 mo.): 62 mph
- April 2014 (age 13 yrs, 3 mo.): 70 mph
- June 2015 (age 14 yrs, 5 mo): 75.1 mph
- May 2016 (age 15 yrs, 4 mo.): 80.0 mph
- June 2017 (age 16 yrs, 5 mo.): 86 mph
Hoping for 87 or 88 this summer. Just started lifting, so maybe that will help.
