Hello fellas, I've got a couple of questions I was hoping to get answered. The first is about sit ups, are they bad for your back and what replacement exercise is there which hits the same muscles? I've got to do 45 sit ups (and a bunch of other stuff) for my army fitness test later and I was testing myself just now. I can do it with good form, but I find that it hurts my back and I'd really rather avoid doing it. It's not that lovely good muscle soreness from a good exercise, it just hurts in the wrong way. I don't know if I am doing it wrong (I am mimicing the instruction video as best as I can) or if it is just supposed to hurt and I'm not use to it from not doing the exercise.
I don't really feel it in my muscles anyway. Is it supposed to be a back exercise? A stomach exercise? My deadlift is 140kg at the moment so I am fairly sure my back is not too weak for this simple exercise. All the other physical requirements are really easy for me and I blow the test out of the water except for this one. Like I said, I can do it but it hurts. Any recommendations on how I can either stop being a pussy or use a different exercise to train the same parts?
Secondly, I'm trying to find a good calf exercise I can do at my gym. Unfortunately, it's not an option to leave (everything else is too damn amazing. but there isn't either the seated of standing calf machine which you can put weights onto and my calves are too strong for me to use the stairs to just do them calf step things. I need to be holding at least 20kg in each hand and my grip/hands gets tired before my calves get tired.
Alright, cheers, or thanks as you prefer.
