Any suggestions on a work-out programme for my younger students over the winter months? Which muscles should they be building and how? Should they go for power, strength or stamina or a combination of all three?
Lots (I might LOTS) of ways to go about this.
In my opinion, they should engage in some sort of stretching routine prior to lifting weights. Flexibility is very important. Particularly some stretches that his the lats (back) muscles and traps (upper shoulder, and neck).
Also, for any athletic motion, the lower body is crucial for a stable foundation. When discussing weight lifting, I am big advocate of compound exercises. In general isolating a muscle isn't very effective, although gyms are full of these machines. As such, free weights are the way to go.
Good lower body excercises:
Squat-quite simply the best excercise you can do. If you don't have access to a squat cage, then use dumbbells. Squat down so the quads are PARALLEL to the ground. This is very important!
Stiff legged dead lift-great for hamstrings and lower back. Don't let your back become become arched when doing this and use a very slow tempo for the eccentric movement. You want to feel the stretch here.
Leg press-great for overall lower body power. An effective excercise for really blasting the quads.
Lunges-another all around great excercise. These you can do with dumbbells, or with a barbell across your back. If using the barbell, be careful and I recommend doing this within the squat cage, or perhaps a smith machine.
Tempo/rep pattern:
Depends on the goal. If the objective is strength-high weight, low reps (4-6 reps, 3 sets). Work the muscle in such a way that you can't physically do another rep or two. There's a big difference between failure and muscle fatigue (lactic acid buildup).
Tempo: in general, it should take twice as long on the 'lowering' portion of the repitition than the lifting , or 'raising' portion. You'd be amazed how differently things feel when you minimize momentum.
I prefer to have a routine where I am hitting a different muscle group each day of the week. For example:
Monday - quads, calves, hamstrings
Tuesday - back and traps
Wednesday - bicep and tricep
Thursday - shoulders and forearms
Friday - chest and abs
That's a solid routine and maybe every 4-5 weeks you need to modify things to keep it interesting. Keep track of how much your are lifting and set weekely goals (increase squat by 10 lbs, smooth(er) form on dead lifts, etc).
Cardio should also be sprinkled in. It can be challenging to do cardio right after a weight session since your glycogen stores are somewhat depleted. As such, some people like to do cardio in the mornings, when glycogen stores are already low and the calorie burn is a bit higher and then weight lifting at night (or maybe on the lunch break).
If stamina/weight loss is the goal, then supersetting is the way to go. The idea here is to back and forth from a lower body and upperbody excercise with very little rest in between sets. For instance, you might start out with a leg press (high reps now) and then do seated db presses (military presses). Then go back to the leg press machine and do this 'block' of exercises 3 times over. Always work the big muscles first and progress to the calves, biceps and tricep movements.
I do 4 of these 'blocks.' That's 8 different excercises (and 24 total sets). Couple that with cardio and that's a total body workout that's very challenging.
A sample routine (some call this german body composition routines)...
'A' block
squat (10-12 reps)
barbell military press (10 reps)
'B' block
leg press (12-15 reps)
side lat raise (8-10 reps)
'C' block
leg curl (15 reps)
bicep curl (10 reps)
'D' block
EZ bar curl (12 reps)
decline bench crunches (10-12 reps)
Again, I would start with the squat, do 10 reps, then walk over the military press machine/station do 10 reps, back to the squat, then over to press station, and then one last time for squats and finish up the first block more presses. Before proceeding to 'B' block, rest for 2 minutes. Even though the rep pattern is high, you still want intensity. Thus, this sort of a combination of both failure and fatigue. Keep the weight 'low' enough so you can do about 10 reps, but 'high' enough so we have sufficient intensity to stimulate and recruit all of the fibers. Thus after the 10th or 12th rep, you should feel tired, but bot totally from muscle fatigue. Again, keep a journal of your progress and force yourself to increase the load every few weeks.
