Hey ppl, long time reader, HST-practioner and former poster (new house, machine, career etc means I can't access [or even remember!] my old account :P). I've recently started taking up boxing (used to do a bit of Karate and then MMA back in the day). I'm wondering what the opinions are on the ideal way to maintain muscle mass when during fairly rigorous cardio regimes for ~ 3x45-60min per week, and then 3x steady-pace walks per week, (give or take 45-60min in length ... can't shake these, girlfriend-prerogative has been activated ). Way back when, I remember Lance (is he still around? @ Totentanz and Fausto, Lol, Dan Moore - you probably remember the kid?) used to advocate doing heavy 5's for 6 weeks with 1-2 weeks of negatives added in and the general consensus was lifting heavy is best for reducing // preventing muscle mass loss when cutting (which is essentially what the boxing is going to do). Thoughts, opinions ... ? I keep my workouts to the bigger compound workouts, tend to emphasise Chins//Rows (weighted), Deadlifts, DBell Shoulder Press and Dips (weighted) over Bench, Squats, Lunges and don't pay much attention to minor isolation exercises for the arms, never found them necessary.
