One the food v exercise debate - if your goal is weight loss your efforts are better spent on the food
To put this into hard numbers - most people on the c25k plan run/walk 1.5 - 2 miles per session - peaking about 2.5 miles on the last day. A 2.5 mile run/walk for a 200lb person burns about 300 calories - that 900 per week if you do 3 workouts a week.
It takes 3500 calories to burn off 1 lb of fat so at graduation the program is burning just 1/4 lb per week
A 1200 - 1300 cal a dat diet will create a 700 cal + deficit per DAY
Exercise to get fit - eat to lose weight
The c25k plans is designed to get you running - not fit - it really isn`t enough for fitness
For fitness you should be doing cardio for 40 - 60 mins 5 - 6 times a weeks - this can be anything from you c25k workouts, to extra walking, dancing, boot camps, boxing, eliptical , biking , rowing. Build up slowly - start with 30 mins and add time - yes this will mean doing extra cardio after your running workouts
2 - 3 days a week of weight training will also help you build muscle and boost your metaoblism
Carrie - headaches after running is a sign of dehydration - make sure you try and drink 8 x 8oz of water each day
jen there are many opinions on proper running form - we all have natural form - watch a race and see how people run - some are quite funky ! - the one thing I was told by a coach that has been invaluable whatever you do try and keep your upper body relaxed and land quietly - I did contend at the time it was had to make 200 lbs land lightly - but it is possible - my trainer at the timed helped me by doing a lot of plyometric drills - jumps etc and focussing on landing lightly as opposed to thumping down like a sack of coal ! The other hand advice I got from a coach - when running up hill shorten your stride lean forward and fall up hill - when running down do the opposite ! I actually find running outside easier - I run hills well - I think bigger ( or ex bigger ) people have that potential - lets face we dragging 200 + lbs around - we have strong legs !
Good Luck everyone - you are all awesome - look forward every day - don`t fret if you fall of the plan - just get right back on rack you wont`t have done any real damage
