Workout #1: Pilates

Pilates is a fantastic low-impact workout that focuses on strengthening the muscles while improving flexibility and posture. It targets the core muscles, along with other muscle groups, to create long, lean muscles without adding bulk.

Lie on your back with your legs in a tabletop position and your arms by your sides. Lift your head, neck, and shoulders off the mat and extend your arms straight out in front of you. Pump your arms up and down while inhaling for five counts and exhaling for five counts. Repeat for 10 breath cycles. Aim for three sets of 10 breath cycles.

2. Leg Circles

Lie on your back with one leg extended straight up toward the ceiling and the other leg extended flat on the mat. Circle the extended leg in a controlled motion, keeping the movements small and precise. Perform 10 circles in each direction before switching legs. Complete three sets on each leg.

2. Breaststroke

Begin with your arms extended forward and your legs positioned together behind you. Pull your arms in a circular motion, sweeping them out to the sides and then back together in front of you. As your arms move, perform a frog kick with your legs by bending at the knees and pushing them outward. Complete each stroke with a glide before starting the next one. Do three sets of 100 meters.

3. Water Aerobics

Stand in waist-deep water with your feet shoulder-width apart. Perform a series of exercises such as leg lifts, arm curls, and kicks against the resistance of the water. Aim for 20 repetitions of each exercise and complete three sets.

3. Seated Climbs

Lower the resistance on your stationary bike or find a flat stretch of road. Sit in the saddle and increase your cadence (pedaling speed) while maintaining a moderate resistance.
