Pull-ups
Pull-ups can be done at home or at a gym. Many gyms offer an assisted pull-up machine to provide a little extra support for those not able to do a full pull-up immediately. Pull-ups work upper arm strength and also support core strength.
Running
Running is great aerobic exercise that can improve your strength, stamina and tone. You can run year round on an indoor treadmill. In addition, try variations while running such as distance or interval workouts and also on the terrain with hills.
Pilates
Pilates is a great way to condition yourself for kayaking. Pilates builds strength and flexibility, while keeping your body tone. In addition, many pilates exercises focus on balance which is especially important for kayaking.
Swiss Ball Exercises
Swiss ball exercises are another great kayak conditioning exercises. With a Swiss ball, you can improve your core strength and also balance. Crunches on the ball or straight legged sit-ups while holding the ball work out your stomach muscles and other core areas.
