i agree that it's tough... i'm also focusing on cardio to shed weight so it's even harder (although as i get lighter the running is a bit easier).
i am using the push-pull routine i posted earlier on, training is 1 day on, 1 day off... i run on the off days
currently training for a 5km race, so i run 3 different sets of intervals, run 1 is 5mph & 6mph alternating, run 2 is 5&7 and last is pace at 6...
interval difficulty is increased weekly... so far so good... the reason i am only focusing on the 5km run is 'sprint' nature of the event... my goal is to be under 22 minutes by October of this year, at the same time I am focusing on maintaining peak strength in key movements... while i am not doing low reps, i am focused on things like doing 3 sets of 20 with 225 on bench press...
