I was getting a little tired of the usual push ups and squats modifications, so I decided to incorporate a lunge variation into today's workout to change things up a bit. 

With the skater lunge, keep one leg planted (ex - R leg) then bring your opposite leg back and behind the planted leg, and lower down into a lunge. If jumping or more dynamic movements are still comfortable, you can amp these up by jumping from side to side. Or, if you're not jumping, but want more challenge, switch to a back foot elevated split squat. Not comfortable with the skaters? Regular lunges, squats, stairs are good subs. 

I did elevated tricep dips off of a (sturdy!) patio chair - you can do these with knees extended our knees bent for extra support. Or switch to bent over tricep kick-backs, skull crushers, or banded tricep extensions. 

It was a beautiful sunny day when I did this walk, but if you have limited space, can't leave your kiddos, etc, then stairs or toe taps to stairs (at a speed that is comfortable), or elevated mountain climbers, are good variations. 

I finished this workout with some adductor strengthening. Your adductors (aka inner thigh muscles) are easy to overlook - they don't get nearly the press that your big quads, glutes, and hamstrings get - but they attach to your pelvis right along the forward portion - close to your pubic symphasis (the very center of your pelvis where the two halves come together, which can get really painful with all that extra weight and stretch happening in your later pregnancy) - which make them really important for us to consider! 

I've found that tight muscles are typically weaker muscles (say what?!) and for me, these adductors can get really tight if I don't consciously work on them. So, I finished this workout with: 

3 sets adductor strengthening:

10 elevated glute bridges w/ ball squeeze between my knees. Hold 5 seconds at the top of the bridge while you're really squeezing that ball! 

25 (per side) side lying adductor raises with three seconds hold at the top. 

Let me know if you have questions!
