I wanted to start a kettlebells diary to keep track of my progress and also encourage anybody else who, like me, may not be super-fit already and needs to slow down or modify their program somewhat. It can be done! I have ME and can't really do cardio exercise but realised recently that I can do strength exercises if I'm careful to pace myself. I started swinging with Amy Bento's absolute beginner's workout. Once I got the hang of what I was doing I progressed to Kettleworx. Prior to starting this diary I had completed weeks 1 and 2 resistance and core - my ME means that cardio doesn't agree with me so I skip that one. My husband has started doing KW also and does it three times a week. Some of the modifications that make KW do-able for me: Pause, pause, pause. There's absolutely no shame in pausing during the programme to catch your breath and sip some water. Better to do this and carry on than to give up completely. Modify. Many of the exercises work the whole body and this can result in early tiredness when you are less fit. The legs are the biggest muscles in the body, using the most energy. So, if I'm struggling, I might cut out the leg component on alternate reps. For example: in the squat - arm press move, instead of squat - press - squat - press I'll do squat - press - no squat - press. Use good form. If you do an exercise incorrectly, you could be stressing your body in ways that were not intended and this can result in early fatigue or injury. When a new exercise comes up, do it slowly and focus on your form until you've got it right. Reduce weight. If you're really struggling, better to drop down to a lighter bell (or no bell at all, I do this for turkish getups sometimes) than to quit early.
