When the cold and dark winter months kick in—or when the weather is grim or you’re time-crunched—indoor training is the way to go. However, cycling exclusively on the trainer and doing all of your runs on the treadmill can create imbalances that will appear outdoors.
Do the following workout after your indoor session, two to three times per week.
Ankle mobility is crucial in all three sports—particularly in swimming—and constant treadmill running can wreak havoc on the joint’s flexibility.
Slowly lift your body up onto your tiptoes, and then back down. Repeat three sets of 10 reps with 30 seconds rest in between.
Walk 15 meters rolling the whole bottoms of your feet, from heels to tiptoes. Repeat three to four times with 15 seconds rest in between.
Cycling—particularly on a trainer—produces tightness within your hip flexors. Aside from possible running injuries, tight hips also prevent a streamlined position in the water.
Walking hip opener
Walk for 10 meters, and with each step lift one leg to your chest. Bend the knee of the lifted leg to the outside, and feel the stretch on the hip. Repeat three times with 10 seconds rest in between, then do the same on the other leg.
Get into a lunge position with one knee touching the floor. If you don’t already feel a stretch, bend your torso toward the knee that’s not touching the ground, and arc with your arm. Hold the position for 20 seconds on each side; repeat twice.
After working on mobility, focus on stability and strength. The following basic exercises will help strengthen your smaller muscles and improve your stability and balance, as well as strengthen larger muscles for bike and run.
Start with one foot on the ground and one behind, on a bench. Bend the knee of the leg that is touching the ground. Complete three times, five reps each side, with 30 seconds rest.
Standing upright, lift your right leg parallel to the floor behind you. Bend your torso forward, and extend your left arm in front. Go back to the start, and repeat the set three times with six reps per side and 30 seconds rest.
Having a strong whole-torso core will put you in control of your form for all three disciplines.
Kneel down and place your hands on the floor. Lift your left leg parallel to the floor behind you, and extend your right arm and hand in front of you. It’s like the drinking bird, but on the floor. Repeat the set three times with six reps per side and 30 seconds rest. Increase reps over time.
Start with a front plank (45 seconds on, 15 seconds off), move into a side plank (either side: again 45 seconds on, 15 seconds rest), perform the same on the other side and finish with a reverse plank (45/15 as well).
