One workout, 2 versions. First with weights for the gym and the second using just bodyweight. As ever these can be used stand alone or as a finisher to a bigger session.
Have the bar set to half your bodyweight and do as many Bench Presses as you can with good form, then immediately do as many bodyweight Inverted Rows as possible.
Rest for 2mins then repeat for a total of 5 Rounds.
