Sorry for the delayed reply from your last post back.
Yes he is only competing in the bench lift.
As he is an older lifter I’ve found he does need slightly longer recovery and a 3 day split has seemed to work o.k as weekends are normally out for training.
In this final 6 weeks before competition if he’s doing a max lift day (altering between partial and full range lift and assistant exercises), a shirt day ( with speed bench and assistance exercises), and a final day with just assitance work (back, core,)
Then at the sharp end of the cycle drop this final day out or just reduce the volume?
