Hi Dr. Darden,
Purchased your Extreme HIT and look forward to getting started. In terms of exercise substitutions I wondered at your thoughts on one-armed DB Rows replacing Bentover Rows in the program? Bentover rows always tend to aggravate my back, but I wasn’t sure if doing single-arm exercises is recommended with the 30-10-30 style? My other option would be replacing with resistance band lat pulldowns (unfortunately gyms are still closed in my country so I don’t have access to machine alternatives.). Thanks in advance - I did the 30-10-30 program from Killing Fat earlier this year and really enjoyed it so excited to try this new version!
