Why hill intervals rock!

Tags: , , , , , , ,


Everyone at some poiint has complained about going up a hill.

The reason for this is that they are tough. Used correctly and they will leave you walking like John Wayne for a few days.

This is why I love them. They hurt, they bring fast results and they don’t need much time to finish you off.

But why are they so great and how should they be used for maximum effect?

Why Hill Intervals Should Be A Part Of Any Program

1) The angle of the hill forces a biiiig push off from your glutes to propel you up the hill (assuming your glutes are firing properly). Combined with the stress on your quads, this will turn you into a powerful, more efficient runner whether it is for running itself or for other sports.

The hill angle also takes your ankles through a greater range of dorsiflexion, improving the function of both your ankles and your calf muscles.

2) Time-efficiency. 20 minutes intense conditioning work on a hill will bring better results than a 60 minute plod if you are looking to develop anaerobic endurance and power, and to shed body fat!

3) The intense use of your quadriceps and glutes will results in a large release of HGH which aids in lean muscle growth.

4) A massive oxygen debt will be created due to the lactic acid build up. Your metabolic rate will therefore be elevated for a long time afterwards resulting in lower body fat levels (assuming you have control of your nutrition!)

5) Hills are superior to steps in my opinion because most steps are quite close together meaning you train yourself to take small steps rather than opening out your hips over a greater ROM. Of course if you find some ‘deep’ steps (from front to back) that takes care of this!

6) If you are moving into a period of training when you don’t want to be detracting from running / sport specific conditioning time, hill intervals are great because they will enable you to maintain or even build sport specific strength levels. Performing heavy weights in a seperate session may leave you flat when it comes to sport specific training which isn’t much use!

7) Hill running will do wonders for your lactate threshold or less scientific terms ‘the burn’!

Words Of Warning

1) If you have poor ankle mobility and or tight calves, running up steep hills may cause issues with your knees and hips. If your shins are unable to travel forward over your toes due to poor mobility in the ankle, your knee is likely to be forced to roll inwards causing the hip muscle to lock up. I used to suffer with this and always felt my lower back afterwards. This is a problem running on the flat but compounded by the angle of a hill.

2) Hill running places less emphasis on the hamstrings than flat running so ensure you take steps to counter this. Add in single leg deadlifts and some intervals on the flat to your weekly program.

3) Hill intervals of short bursts with rest inbetween are awesome for many reasons. However, if you are looking to build endurance you are best advised to do longer hills runs with recovery pace in between so you get used to maintaining your running pace as you would have to in a race.

How To Do Hill Intervals

As mentioned above, certain hill intervals are not the best option for everyone. Here are some examples of manipulating rest and work time for your goals….

Explosive sports

If you are looking to improve your explosive power over short distances, you should look to keep the length of your hill interval to around 50m. Perform 10-15 repetitions with the rest being the time to walk back to the bottom.

As you get closer to a competition you may like to increase the distance and jog back down. This may reduce the speed but it will improve your conditioning levels and develop mental strength enabling you to keep going without rest.

This is also a great way to use intervals if you are just in it for fat loss!

If you are involved in MMA for instance, you might do a 100m sprint taking 20-30 seconds and jog back down until 5 minutes is up. Rest 1 minute then start again.

Runners

If you are a 1500-5000m runner who needs high levels of anaerobic endurancem 10-15 x 200-400m at 3-5k pace with 45-60 seconds rest will do the job. The longer your race, the higher up the distance and slower the pace you should use. As you get closer to race day, reduce the rest intervals to around 30 seconds or use active recovery between runs.

If you are looking to improve 10k pace, you are best advised to use a pace which enables you to keep running between – your recovery time should be about the same as the time it takes you to run up the hill. This means the pace is technically the same on the way down as on the way up but obviously it is much harder to keep this pace on the way up the hill!

Run a distance that takes about 45 seconds at about 5-10% over your 10k pace. Repeat 12-16 times.

Hill intervals feature in Intense Conditioning because they are so effective!

How to train like an elite runner

Tags: , , ,


Whether you are into running or not, it’s always good to find out how elite athlete’s do it!

I hooked up with Lee Merrien a British cross-country athlete who is also a sub 4-minute miler.

Intervals to improve 10k times

Lee’s got body fat of around 5% but shock horror he eats lots of potatoes which have been outlawed by a lot of fat loss experts and coaches.

This is a sample week of Lee’s training….

Mon

AM 45-60mins run
PM 20mins jogging, drills & 8 x 80m hill sprints plus core/glut exercises

Tue

AM 40mins easy.
PM track interval session(15-20′ jog, dynamic warm up & drills then main session. Cool down 15′ easy

Wed

AM 60-90 mins
PM weights, consisting of foam roller, corrective flexibility, dynamic warm up then strength exercises, usually reps of 10

Thur

AM 40′ easy
PM 50-60′ as threshold run or progressive run over latter part of run.

Fri

45′ very easy or rest

Sat

AM track or grass based interval workout
PM 40 min easy run

Sun

AM long run approx 1hr 45

*** Subsrcibers to the blog (see top right) received a 3 week 10k program straight from Lee! Get on board!***

Here’s what else he had to say….

Why Killer Intervals Should Be The Basis Of Any Conditioning Program

Tags: , , , ,


Here’s some evidence as to why interval training must be a regular, tough, sweat-fest of a session on your training timetable!

This really is just some of the piles of research I have next to me!

Let’s look at some answers to sceptics, aerobics fans and those who ‘don’t have time’…

But I want to improve my stamina for running / cycling etc

Gibala et al (2006) compared low volume sprint training with high volume endurance (typical of running fanatics).

Both groups performed 6 sessions over 14 days.

The HIIT group performed 4-6 x 30 second intervals @ 250% of VO2 max (very hard!) with 4 min rest inbetween.

The endurance group performed 90-120 min cycling at 65% of VO2 max (moderate).

The HIIT group did 2.5 hours of training over 2 weeks whilst the endurance group did 10.5h.

The results?

Muscle oxidative capacity improvements was similar in both groups so muscle endurance capabilities will have improved at about the same rate, but the HIIT group spent 8 hours less doing it over 2 weeks!

Aerobic exercise burns fat so it’s better for fat burning

5 well trained distance runners were tested at each of the following:

2 hours @ 24% of VO2 max (low intensity)
10 minutes @ 81% of VO2 max (relatively high intensity but continuous)
2 minutes on 2 minutes off @ 89% of VO2 max (high intensity intervals)

(Brockman et al, 1993)

After one hour of finishing the sessions, oxygen consumption was significantly higher following the intermittent exercise.

After just 40 minutes, oxygen consumption had returned to base level in the walking test. This means no more fat burning until you do mroe exercise.

This means metabolic rate was much higher – more calorie / fat burning whilst at rest!

I’ve heard you burn more calories at the time of aerobic exercise.

This MAY be true but check this study out!

A 20 week endurance program was compared with a 15 week High Intensity Interval Training program. (Tremblay et al, 1994)

Over those weeks, the endurance group burned 120mJ of energy during exercise whereas the HIIT group burned 57.9mJ.

Surely endurance wins then?

Not when you consider that the HIIT group showed more pronounced reduction in body fat!

So they trained for 5 weeks less but lost more fat – SHORTER TIME TO RESULTS!

When they adjusted the results to compare fat loss in proportion to the cost of energy of the exercise sessions, the HIIT group lost 9 TIMES as much fat.

It should be pretty clear now why I force home the point that how many calories you burn in a session is largely irrelevant – ignore calorie counters on cross-trainers etc – waste of time.

Get in, smash it, go home.
