Ive had shin splint for the past month ( i was training on and off because of it, couldnt get used to not running...it was a big shock) Ive now stopped running , Because i would rather be injury free and be *able* to train , rather then be fit ...but have an injury. Ive started cycling , and i intend to do this 6 days a week for 30 mins at a heart rate of 80%+ of max heart rate (80% = Cardio) Ive got a bit of pain/stiffness in my calf , but im sure that will go in time , i think its a straned or something ...but im doing low impact cycling so it should go. Am i rite in thinking that if i was to go to basic training (for the rifles) and i got a time of say 12-13 mins (Prop wont ...but if worst comes to worst) would i still get to be in basic and not get kicked out, As a junnier it says under 14mins(wich i could do easy without training)....but...if worst come to worst. Also is doing 30 mins cycling(machine at gym)at 80%+ of max heart rate (cardio) the same as running for 30mins at say 80%+ .......Will the fittnes gains....be the same ? Im and quite annoyed because i was running 6 miles...and running lots etc and know im not...but all i can hope for is to be injury free and as fit as i can be ....got to stop thinking about "what i could do " Press ups - i can do 30 in a row without stopping ...just done 3 sets of them ( dont no rest time, but i done 30 , then went to get a drink done another 30 m, writting some of this and got anoter drink and done 30) Sit ups - Easy ...50+ ( dont even do them ) Thanks in advance.
