Played badminton against Ronny today. First game against him in years. Won four straight sets, much thanks to him lacking "cardio".
Badminton is good for me, forces me to work with finesse, or try to. Lifting, circuits & cardio is mostly grunt work. If I wrestle I try to out-muscle the opponent, if I play soccer I try to out-run the opponents. In badminton (or volleyboll or tennis) that is not an option.
