Below are the exercises and then some of the problems my clients express about the holidays.

1) Oblique pushup
Assume modified push up position with forearms resting on floor (plank position), elbows under shoulders and bent at 90 degrees. Keep torso steady and tight. Lift right arm out and up toward ceiling (keeping bent at 90 degrees) while twisting the torso toward ceiling also. Bring arm back to starting position and switch.
2) Leg row
Sit on ground with hands on top of head, bend knees and lean back slightly. Keep your torso still and tight while extending your legs out and then bring them back in.
3) Alphabet abs
Lying on your back with one leg bent (knee up) for stability, take the other leg, extend it out and write the alphabet allowing the heel to lead the movement. This one takes a little time but you will feel it.
4) On all 4's
Get on your hands and knees and bring 1 knee forward into your chest and then extend it straight back all the way. Do all the reps on one side then switch.
5) Rope climb
Sit on the ground with your legs extended and knees bent, dig in your heels for stability and lean back slightly. Tighten your core, reach your arms up toward the ceiling and start pulling back toward your face one arm at a time, really stretch those arms up.
Some of my clients express to me that their biggest challenge is the family gatherings of course. They say the food is so great and so much of it that they find it hard to pass anything up. I let them know that its ok to attend those gatherings but try not to focus on the food but on the guests that are there.
Try to stay out of the kitchen when everybody is dropping their food in and spend some quality time talking to family and friends that you haven't seen in a while. I also advise them to eat their regular meals throughout the day up until the gathering and don't starve themselves and save it for the big meal. If they usually eat 5-6 small meals throughout the day and it really depends on when the gathering is, maybe eat 2-3 before they attend, then they won't be so hungry and ready to gobble everything in sight and again it depends on when the meal is, may eat a little something later or nothing more for the day.
I also advise them to drink plenty of water, it will fill them up and no additional calories are added to what they will be eating. If its someone who is currently not working out, there is no reason not to get started now instead of waiting for the new year. If they get started now, they may not lose any weight but at least they can maintain and not gain that extra 5-10 pounds during the holidays, which of course makes it just that much harder to lose.
When they sit down for that big meal, eat the stuff that’s good for you like the healthy meats, vegetables, whole grains and fruit. They don't have to pass up all the not so good for you stuff, but just take a little and watch your portion controls. Just remember to eat when you are hungry and stop just short of when you are full. Take a nice walk afterwards and invite the family along.
