Yep, I do a weekly gym workout too with the following exercises:
30 Pressups
9 Wide arm chin ups
12 reps lat raises (side 8Kg dumbells)
12 reps fwd raises (8 Kg dumbells)
20 reps each arm bent over rowing with 20Kg dumbell
I also shoulder press my 5 year old son weekly: 12 reps (not joking
)
Barbell Squats 60Kg (40kg on a 20kg bar) 10-12 reps
Hamstring machine (difficult to quantify weight, circa 30Kgs?) 12 reps
Bent leg situps 60 reps
Crunch situps 50 reps
For my calves I do daily eccentric exercises on stairs
This lot pretty much exercises all the muscle groups I can think of. My intention in respect of upper body exercises is to maintain muscle, not build. The leg exercises are pretty tough.....12 reps is failure. I do intend these to be to a degree strengthening; in order to aid with hill work/speedwork.
I'm 5'9 and just under 11 stone (152Lbs). I'm training for a sub 36:30 10K in 2 weeks.....fingers crossed!!
