Just wrapped up BTS3. I ran it two days a week, instead of 3, alongside 2 days a week of AXE 1-hand swings.
This took me 12 weeks to complete instead of 8 weeks, as per the program.
This proved to be a good run, the 2 days a week were no problem to recovery from. The AXE sessions are also structured (as long as you pay attention to stop signs) that recover is enhanced.
Results:
1) Barbell Press - 105lb, original test 6 reps, after program 7 reps
2) Zercher Squats - 185lb, original test 5 reps, after program 6 reps
3) Weighted Ring Chinups - +4kg, original test 5 reps, after program 6 reps
All in all, I was happy with the results, even if they were small gains. I was hoping for at least strength maintenance (knowing I was only doing 2 sessions a week instead of 3), but was happy to gain a little strength.
I am planning on rotating in either BTS3 or BTS4 a few times a year. Very happy with Fabio Zonin's programs, in fact I'm about to run Reload again, so I can focus on strength.
