Bob knows that. But he's got great ideas for winter wonderland workouts.
Biggest Loser trainers reveal below two of their favorite moves for flattening your abs--no matter what your fitness level.
Squats
Stand with legs a comfortable distance apart and arms crossed over chest. Keep back straight, being careful not to round spine. Bend knees, squatting down until thighs are almost parallel to floor. Do not extend knees past toes. Press up from heels and return to starting position.
Beginner: 1 set of 10 to 12 reps
Intermediate: 2 sets of 10 to 12 reps
Advanced: 3 sets of 10 to 12 reps, holding dumbbells at sides
Plie Squats
Stand with feet slightly farther than hip-width apart, with toes and knees turned out comfortably and aligned with each other. Keep back straight. Bend knees and squat, lowering hips keeping pelvis steady. Keep abs contracted. Press up from heels and straighten legs back to starting position.
Beginner: 1 set of 10 to 12 reps
Intermediate: 2 sets of 10 to 12 reps
Advanced: 3 sets of 10 to 12 reps, holding dumbbells
